Creating a link on Android didn't work: the popover's URL never became a link and focus jumped to the next editor instead. The cause is that a mobile IME picks the action its Enter key performs, and with a lone text field it picks "Next" — advancing focus and dispatching no key event at all. A popover that only listens for Enter therefore has nothing to hear. Putting the fields in a real `<form>` is what makes the IME offer a submitting action instead, confirmed on a device; `Form.Root` was a `<div>`, so `onSubmit` could never fire. `Form.Root` now renders a `<form>`, and submission runs off its `submit` event. That has three consequences worth calling out: - HTML only submits implicitly when a form has a submit button or exactly one field, so the link *edit* form — url plus title — would still reach nothing. `Form.Root` renders a submit button to cover any field count. It is visually hidden rather than absent so assistive technology still has a labelled control, and outside the tab order so sighted keyboard users never land on a control they can't see. - The browser performs implicit submission for an Enter that arrives with `isComposing: true`, so accepting an IME candidate would submit the popover mid-word. `useFormSubmit` guards that centrally, replacing the per-callsite `isComposing` checks that had already drifted apart. - With one submission path, the five Enter handlers are redundant and are removed. `EmbedTab` had no form at all and gains one; the AI prompt menu's handler and `onSubmit` disagreed about whether Enter picks the highlighted suggestion or submits the typed text, and now share one decision. `TextInput` also loses its `onSubmit` prop: every skin forwarded it to the `<input>`, and `submit` only fires on a form and bubbles upward, so it could never have fired. `EditLinkMenuItems` passed it, which is plausibly why the gap went unnoticed.
Review follow-ups: - The embed panel ended up with two submit controls: its own Embed button plus the hidden one `Form.Root` adds, so a screen reader announced two separate actions for the one thing that panel does. `Form.Root` now takes `hasOwnSubmitButton` for callers that supply their own. - The three `TextInput`s hand-rolled ref merging. `mergeRefs` already exists here, but returns a fresh callback per call — which detaches and reattaches the ref every render — so this adds `useMergeRefs` alongside it, memoized the way `react-merge-refs` does, and uses that. - The mantine popover keyed two behaviours off `portalRoot` while its comments explained them in terms of mobile. Same condition, but named, so the reason isn't hidden behind an unrelated prop. - `useFormSubmit` documents that it exists for `Form.Root` implementations rather than applications.
…'t fail Second review round, checking whether the tests added in the first one can actually fail. Two could not: - The composition tests built a synthetic form replicating what `Form.Root` does, so deleting the guard from `useFormSubmit` left them all green — the shipped code had no coverage at all. A test now drives the real link popover through a CDP composition, and fails when the guard is removed. The synthetic ones stay as what they are: the platform fact that a browser submits for an Enter carrying `isComposing: true`. - "the embed tab commits exactly once" asserted one image was present, which is true whether the update ran once or twice. Its replacement counted the form's submit events, but that cannot fail either: only mantine runs in this suite and its panel button already defaults to `type="button"`. The structural check — no button inside the form — is what actually guards both the double-commit and the duplicate-control problems, and it does fail when the button is moved inside, so that one is kept and the outcome-based tests are dropped rather than left as decoration. Also renames `hasOwnSubmitButton` to `omitSubmitButton`: EmbedTab's button sits outside the form, so the form has no submit button at all and relies on single-field implicit submission. The old name asserted something untrue of its only caller, and hid the constraint the flag carries.
…es IMEs The guard answered the wrong category of problem. `isComposing` checks are needed in *keydown* handlers, because an IME-consumed key still dispatches to JS — that is what the five removed Enter handlers were. Native form submission never sees that key: the IME consumes the confirming Enter (it reaches the page as keyCode 229, which the browser runs no default action for), so implicit submission cannot fire mid-composition. This is why no plain form on the web carries composition handling. The state the guard defended — composition open, unconsumed trusted Enter delivered — is one only CDP emulation can fabricate: `imeSetComposition` sets composition state with no IME in the loop to consume the key. No real IME produces the sequence. Worse, the guard carried real risk in the other direction: Gboard's action key commits the composition and submits in one press, so if any IME delivers `submit` before `compositionend`, the guard would swallow a legitimate submission — the original bug, reintroduced for exactly the users it claimed to protect. `Form.Root` goes back to plain `preventDefault` wiring, `useFormSubmit` is deleted, and the composition tests now pin the *native* contract against the real popover: accepting a candidate does not submit, Enter afterwards does.
Form.Root's optional omitSubmitButton becomes a required
submitButton: ReactElement | "none" — the compiler now forces every
caller to decide the form's one submit affordance instead of a boolean
opt-out defaulting silently (ReactElement, not ReactNode, so the
"none" sentinel can't be satisfied by an arbitrary string).
@blocknote/react owns the default control (ScreenReaderOnlySubmit,
which reads the dictionary) and its clip CSS, in one copy; the three
skin Forms collapse to rendering whatever they're given.
The embed tab shows why: its visible button is now the form's
submitButton — inside the <form>, one commit path for click, Enter and
a mobile IME's action key, one labelled action for assistive
technology. That required FilePanel.Button to take an explicit
type ("button" | "submit"): the skins disagreed on the default
(shadcn hardcoded submit, Mantine defaults to button), which is exactly
what had forced the button outside the form before.
Layout-wise the <form> is a semantic wrapper only, never a box: every
skin renders it as class bn-form and one shared rule gives it
display: contents. Ariakit and shadcn rendered no wrapper element at
all before the real <form> arrived, so their flex+gap containers
(popover contents, the file panel's tab column) lay out fields as
direct children; mantine's containers are block, making contents a
no-op there — verified per skin against computed layout.
Breaking (release notes): Form.Root requires submitButton;
FilePanel.Button requires type. The pointer:coarse input sizing in the
same stylesheet region is from #2982.
implicitSubmit and compositionSubmit assert browser behavior against raw createElement fixtures — nothing BlockNote in them — so they move out of form/ into end-to-end/platform/ with a README stating the contract: these are the per-engine platform facts Form.Root's design rests on, and a red test here after a browser update points at the platform fact that moved, not at BlockNote.
The portalRoot-implies-mobile inference in Popover gets a TODO pending the portalling discussion. TextInput documents why its manual preventScroll focus and Mantine's traps can never fight: no trap runs in the form popovers at all (Popover's trapFocus defaults to false), and in trap-active subtrees nearby (toolbar Tab-cycling, desktop menus) the data-autofocus attribute makes a trap pick this same element.
From review: the manual focus block was copy-pasted across the three
skins and had already drifted (mantine's copy had grown a comment and a
data-autofocus attribute the others lacked). The hook in @blocknote/react
now owns the ref, the focus({ preventScroll: true }) effect, and the
rationale — including how the official implementations compare (React's
autoFocus is a bare .focus() at commit, which is exactly the scroll-yank
this exists to avoid; Mantine defers via setTimeout; floating-ui via
microtask + rAF) and why no extra deferral is used here: nothing to wait
for, and added hops erode the user-gesture window in which iOS Safari
lets a programmatic focus open the keyboard (validated on real iOS).
data-autofocus is set per skin only where the UI library reads it:
Mantine's focus trap and Ariakit's dialog initial-focus both select it
(Ariakit's popovers run autoFocusOnShow by default, so the attribute
makes their pick explicit instead of positional); shadcn's Base UI has
no attribute convention — its mechanism is the initialFocus prop — so
that skin omits it.
- EmbedTab's submit callback renamed to handleSubmit (consistency with EditLinkMenuItems). - The Form contract docs in ComponentsContext trimmed to the contract; the device-verified rationale lives in the PR and its tests. - One focus principle across skins, now enforced rather than raced: BlockNote owns focus in its popovers (useAutoFocus). Ariakit's autoFocusOnShow is disabled — its default bare-focuses the first tabbable (no preventScroll, plus a Safari scrollIntoView), the exact scroll-yank useAutoFocus avoids, previously masked only by effect ordering. Mantine's popover trapFocus pinned to its (identical) default, dead ternary dropped. data-autofocus stays only where the library reads it AND focuses safely — Mantine's trap; Ariakit fails the second test, Base UI the first.
The portal rework meets this layer's popover focus ownership: the adapters
keep `autoFocusOnShow={false}` / `trapFocus={false}` (BlockNote owns focus
through `useAutoFocus`) and take the required `portalElement`.
One translation beyond conflict resolution: Mantine's `hideDetached={false}`
— which keeps the link popover alive through the virtual-keyboard viewport
resize on Android — was gated on "a portal root was passed", which meant
"mobile toolbar" only while nothing else passed one. Every popover now
does, so it is gated on `preventFocusOnOpen`, set for exactly the
mobile-toolbar popovers.
…effects A parent's layout effect runs after its children's. Ariakit picks the mount point of its eagerly rendered popovers in a layout effect and re-parents a still-detached portal element to document.body, outside the editor's registered UI: on the mobile toolbar that took the toolbar's anchor and the link popover with it, so focus in the URL input read as outside the editor and the toolbar unmounted. Attaching, theming and registering the override root in an insertion effect puts it in the document before any layout effect in the tree runs.
… focus
preventFocusOnTap (exported from @blocknote/react) replaces the per-skin
copies of the touch guard on toolbar buttons and dropdown triggers: on touch
it cancels the focus move of a tap while the click still fires, on Safari it
focuses the button like other browsers do.
Popovers never take focus from the UI library, on any device, in all three
skins: BlockNote owns focus in its popovers through useAutoFocus on the input
that wants it. Mantine already had trapFocus off, Ariakit autoFocusOnShow off
(now with unmountOnHide, so the hook runs on open instead of once on hidden
content), shadcn now passes initialFocus={false}. That leaves nothing for
preventFocusOnOpen to do on Popover.Root, so the prop is removed there and
from the buttons that passed it. Mantine's hideDetached is off as well: the
floating wrapper already hides on a hidden reference, and the on-screen
keyboard's viewport resize made Mantine hide the dropdown and blur its input.
Makes preventFocusOnOpen hold for menus and selects on the ariakit and shadcn skins; only Mantine honoured it. Ariakit: autoFocusOnShow as a callback (a plain false defers to the store flag its MenuButton sets on click), autoFocusOnHide off, items do not focus on hover or tap. shadcn: Base UI has no initialFocus on Menu or Select, by design upstream, so the popup hands focus straight back to the editor inside the same focus dispatch, item hover highlighting is off, items do not focus on tap. Both skins' toolbar buttons spread the library's props first and forward its injected onMouseDown, so the tap guard is never replaced and Base UI's mousedown-opened menus still open. The android skinFocus suite pins it per skin: tapping a button, opening the block type select or the colors menu, picking from them, and the link button handing focus to the URL input, none of which may leave the editor.

…ing on a device Removing Ariakit's autoFocusOnHide override on the menu and select, and Base UI's highlightItemOnHover override on the menu and select, changes nothing on Android (Chrome) or iOS (Safari) with the mobile toolbar: focus never enters the popup, so there is nothing to return on close, and the item mousedown guard already keeps a tap's compat mousemove from focusing anything. Verified with the android e2e instance, a phone and the iOS simulator.
No menu on the mobile toolbar has a sub-menu, and Base UI does not focus a sub-menu on open; taps on its items are already covered by preventFocusOnTap. Also documents how to test Mantine's hideDetached override on a device.
…oad-bearing One line each: what goes wrong on the mobile toolbar without the prop, and which skinFocus case covers it. The forwarding comments on the toolbar buttons are gone, calling the library's injected handler needs no defence; the spread order keeps a one-liner. preventFocusOnTap points to the possible follow-up in focus-management.md.

Ariakit v0.4.27 Menu autoFocusOnShow false callback release notes
💡 Result:
In Ariakit version 0.4.27, a fix was implemented for the Menu component regarding the autoFocusOnShow prop [1][2]. The release notes state that the Menu component was updated to correctly respect the autoFocusOnShow prop when it is set to false or when a callback returns false [1][2]. While this change prevents the menu from automatically focusing on show when configured to do so, it maintains the ability for users to use arrow keys to move focus into an already-open menu [1][2]. This update was released to address issues where the autoFocusOnShow prop was not being properly observed, causing the menu to receive focus despite being explicitly configured otherwise [3].

…ry injects Ariakit and Base UI clone a render element and merge the trigger's HTML attributes, handlers and ref into it, so the toolbar buttons receive those on top of the generic Button props at runtime; the declared props type said otherwise and the mousedown forwarding read it through a cast. The buttons are now typed as the generic props plus HTMLAttributes and take onMouseDown by name. The assertEmpty guard stays on the remainder with the injected keys omitted, so a forgotten generic prop still fails to compile.

to the mobile focus-suppression case, preserving Mantine’s default
detached-dropdown behavior for other popovers such as EmojiPicker. Update the
shared adapter’s configuration or expose a scoped option so non-mobile popovers
retain hideDetached=true while the mobile toolbar behavior remains unchanged.

The bug
Creating a link on Android didn't work: the URL never became a link and focus jumped to the next editor. A mobile IME picks what its Enter key does — with a lone text field outside a form it picks "Next": advance focus, no key event at all. A popover listening for Enter has nothing to hear. Being inside a real
<form>is what makes the IME offer a submitting action instead (verified on a physical device, withenterkeyhintruled out as the cause) — andForm.Rootwas a<div>, so itsonSubmitcould never fire.The fix
Form.Rootrenders a real<form>; submission runs off itssubmitevent. Three consequences, each pinned by tests:Form.RootrequiressubmitButton: ReactElement | "none", withScreenReaderOnlySubmitin@blocknote/reactas the standard control (visually hidden — clipped, notdisplay:none— so assistive technology keeps a labelled control;tabIndex={-1}so sighted keyboard users never land on an invisible tab stop; CSS and dictionary in one copy instead of per skin). The embed tab passes its real button as thesubmitButton— inside the form, one commit path for click/Enter/IME-action, one labelled action — which also forcedFilePanel.Buttonto take an explicittype(the skins disagreed on the default, which is what had exiled the button from the form in the first place).isComposingchecks the old keydown handlers carried don't transfer to the submit path. The tests pin the native contract against the real popover: accepting a candidate does not submit, Enter afterwards does.EmbedTabhad no form at all and gains one; the AI prompt menu's handler andonSubmitdisagreed on whether Enter picks the highlighted suggestion or submits the raw text, and now share one decision.Also:
TextInputloses itsonSubmitprop — every skin forwarded it onto the<input>, wheresubmitnever fires, so it was dead since #652 (and plausibly why the gap went unnoticed).Notes for review
Form.RootrequiressubmitButton(replaces the earlier optional opt-out),FilePanel.Buttonrequirestype, and the new dictionary keygeneric.form_submit(the submit control's accessible name) makes hand-rolled dictionaries a compile error until added. The 23 non-English translations are machine-generated and unreviewed.mobile/linkSubmit.test.tsx) — exactly what the IME's submitting action does — but which action the IME itself offers is an OS decision no emulation can observe. That half is on the manual release checklist (testing skill);linkSubmit.test.tsx's header documents the boundary. A device suite automating it exists parked onmobile/emulator-layer(test(device): local emulator layer — real Chrome/Gboard as normal CI #3034).end-to-end/platform/directory (rawcreateElementfixtures, nothing BlockNote — the README states the contract): implicit-submission rules and composition behaviour, per engine, on the desktop engines and the emulated-android instance alike. All fixes proven red-first (details in commit messages).What fixes the keyboard collapse on focus
Asked in review: the description covers form submission, but the popover no longer collapses the virtual keyboard when focus moves into its input. Which change does that?
The one-line
hideDetachedgate in the MantinePopoveradapter (packages/mantine/src/popover/Popover.tsx). Mantine'sPopoverdefaultshideDetachedtotrue: when the target is considered detached, it setsdisplay: noneon the still-mounted dropdown. The on-screen keyboard opening resizes the viewport, Mantine treats that as detached, the dropdown goesdisplay: none, a hidden ancestor cannot hold focus, so the URL input blurs, the toolbar unmounts with it, and the keyboard closes. That is the whole cascade.hideDetached={preventFocusOnOpen ? false : undefined}turns it off for exactly the popovers that live in the mobile toolbar (preventFocusOnOpenis set for those and nothing else); desktop keeps Mantine's default. Diagnosed in #3025, carried here with the popover work. Ariakit and shadcn never had the behaviour, which is why the skinParity suite only pins the Mantine flow throughmobileToolbar.test.tsx.Focus on the mobile toolbar, all three skins
This layer also makes
preventFocusOnOpenhold on the ariakit and shadcn skins (only Mantine honoured it), and settles what takes focus where. The model is written up inpackages/react/src/editor/focus-management.md; the short version:autoFocusinputtrapFocusoff, AriakitautoFocusOnShowoff, shadcn now passesinitialFocus={false}. BlockNote owns focus in its popovers throughuseAutoFocuson the input that wants it. That leaves nothing forpreventFocusOnOpento do onPopover.Root, so the prop is removed there and from the buttons that passed it (breaking for custom skins that read it: it was unreleased).preventFocusOnOpenset by the mobile toolbar):autoFocusOnShow={() => false}on the menu (a plainfalsedefers to a store flag Ariakit's MenuButton sets on click),autoFocusOnShow={!preventFocusOnOpen}on the select popover, items and options do not focus on hover; the popover getsunmountOnHide, since Ariakit keeps closed popover content mounted anduseAutoFocusfired once on the hidden URL input and never again, which is what broke desktop ariakit link creation too.initialFocuson Menu or Select, by design upstream ([menu] button is focused when menu is opened mui/base-ui#2143, [Collaboration] Make yjs provider composable #714), so the popup hands focus straight back to the editor inside the same focus dispatch (onFocusCapture,packages/shadcn/src/lib/preventFocusOnOpen.ts). Traced on a real Android device: without it the popup focuses, the keyboard closes, the toolbar and popup are gone about 150 ms after opening.preventFocusOnTapexported from@blocknote/react, replaces the per-skin copies on toolbar buttons, dropdown triggers, menu items and select options: on touch it cancels the focus move of a tap while the click still fires, on Safari it focuses the button like other browsers do. The ariakit and shadcn toolbar buttons spread the library's props first and forward its injectedonMouseDown, so the guard is never replaced and Base UI's mousedown-opened menus still open.hideDetachedis off unconditionally (replaces the gate described in the section below): BlockNote'sGenericPopoveralready hides floating UI on a hidden reference, and on the phone the keyboard's viewport resize made Mantine hide the dropdown and blur its input.PortalElementOverrideattaches, themes and registers its root in an insertion effect. A parent's layout effect runs after its children's, and Ariakit picks the mount point of its eagerly rendered popovers in a layout effect, re-parenting a still-detached root todocument.body, outside the editor's registered UI; on the mobile toolbar that took the link popover with it and the toolbar unmounted on the URL input's focus.skinFocuscase that covers it.Tests:
tests/src/end-to-end/mobile/skinFocus.test.tsxon the android instance, per skin: tapping a button never moves focus onto it, the link button hands focus to the URL input, opening the block type select or the colors menu keeps focus in the editor, picking from each leaves it there. Each case was red on the skin it pins before the change. The portal pin test inportalElements.test.tsxfails with a layout effect.Summary by CodeRabbit
