Can you write a test showing the underlying issue instead of testing implementation details (nesting depth)?

sorry about that, I was stumped on it for a little bit
I got there today though, just needed to sleep on it. done.

##### Fixed the react compiler preset filter to be linear ([#​1353](https://github.com/vitejs/vite-plugin-react/pull/1353))
The improved filter in v6.0.3 was non-linear and caused a performance regression ([#​1349](https://github.com/vitejs/vite-plugin-react/issues/1349)). The filter was changed to be linear to avoid that.

##### Improve the react compiler preset filter to reduce false-positives ([#​1138](https://github.com/vitejs/vite-plugin-react/pull/1138))
Improved the filter in the react compiler babel preset to reduce the false-positives so that less modules are processed by the react compiler.

[Compare Source](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/compare/v0.5.6...v0.5.7)
##### Add `allowCompoundComponents` option ([#​117](https://github.com/ArnaudBarre/eslint-plugin-react-refresh/pull/117))
> Default: `false` (`true` in `vite` config)
Don't warn when components are exported as an object gathering them. Every member of the object must be a component, and a member holding an anonymous function requires a component name as key.
This should be enabled if the fast refresh implementation correctly handles this case. Vite supports it since `@vitejs/plugin-react` 4.7.0, `@vitejs/plugin-react-swc` 3.11.0.
```json
{
"react-refresh/only-export-components": [
"error",
{ "allowCompoundComponents": true }
]
}
```
Enabling this option allows code such as the following:
```jsx
const Root = () => <></>;
const Label = () => <></>;
export const Tag = { Root, Label };
```

[Compare Source](https://github.com/i18next/i18next-http-backend/compare/v3.0.5...v3.0.6)
- fix: allow forward slashes in `ns` values so nested namespace names (mapping to URL layouts such as `/locales/en/a/b.json`) fetch correctly again. 3.0.5's security fix applied the same strict URL-segment check to both `lng` and `ns`, which was correct for `lng` (no BCP-47 shape contains `/`) but over-strict for `ns` — nested namespaces containing `/` were never officially supported, but the behaviour fell out of the implicit string-substitution semantics of `loadPath` and is common enough in the wild to be worth accommodating. `isSafeUrlSegment` is now split into `isSafeLangUrlSegment` (strict — still rejects `/`) and `isSafeNsUrlSegment` (loose — allows `/` but still rejects `..`, `\`, URL-structure characters, control chars, prototype keys, and oversized inputs). `isSafeUrlSegment` is kept as a backwards-compatible alias for the strict check. The 3.0.5 security fix remains in force for every concrete attack pattern from the original advisory.

[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.13...v17.0.14)
- fix: the `i18n` object returned by `useTranslation` was only refreshed when `i18n.language` changed, so a `resolvedLanguage` (or `languages`) change of its own kept handing components the previous snapshot. That happens whenever the translations for the current language arrive after the switch — i18next resolves to the fallback until its store has them — and components reading `i18n.resolvedLanguage` (language switchers, for example) then stayed one switch behind. The cached wrapper is now keyed on all three language fields, which are exactly the ones the surrounding `useMemo` already depends on; wrapper identity still only changes when the language state does, so the caching from [#​1885](https://github.com/i18next/react-i18next/issues/1885) is unaffected. Reported via [next-i18next#2348](https://github.com/i18next/next-i18next/issues/2348).

- fix(types): the selector-form `keyPrefix` overload of `useTranslation()` is now available under `enableSelector: 'strict'`. `useTranslation` was gated on `true | 'optimize'` only, so under `'strict'` it resolved to the legacy signature and the selector overload disappeared entirely (`keyPrefix: ($) => $.ns.foo` failed with `Type '($: any) => any' is not assignable to type 'undefined'`). `Trans` already handled all three modes. Companion to the same fix for `getFixedT` in [i18next#2446](https://github.com/i18next/i18next/pull/2446). Thanks [@​hovelopin](https://github.com/hovelopin) ([#​1930](https://github.com/i18next/react-i18next/pull/1930)).

[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.11...v17.0.12)
- fix(IcuTrans): key-less `icu.macro` nodes (`<Trans>Welcome, {name}!</Trans>`, `<Select>`, `<Plural>` without `i18nKey`) rendered an empty string since 17.0.0. The macro now emits `<IcuTrans defaultTranslation="…">` without a key and `IcuTrans` passed `undefined` to `t()`, which returns `''`. Like `Trans`, `IcuTrans` now uses `defaultTranslation` as the key when `i18nKey` is not provided.
### [`v17.0.11`](https://github.com/i18next/react-i18next/blob/HEAD/CHANGELOG.md#17011)
[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.10...v17.0.11)
- chore: `html-parse-stringify` updated to `^4.0.1`. The parser powering `<Trans>` is now actively maintained under the i18next org ([i18next/html-parse-stringify](https://github.com/i18next/html-parse-stringify)) after years without upstream releases. 4.x brings modern dual ESM/CJS packaging with an `exports` map, zero runtime dependencies, reworked TypeScript types and a long list of parser fixes (literal `<` in text, multiline/CRLF attribute values, comments containing `>`, doctype handling, quote-aware bracket handling).
- refactor(Trans): the internal `escapeLiteralLessThan` scanner (\~80 lines) is replaced by the parser's new `allowedTags` option with identical semantics: only numbered tags, kept basic HTML tags and known component names are parsed as markup, any other tag-shaped sequence in the translation stays literal text. Rendered output is unchanged (all 493 tests pass, including the [#​1880](https://github.com/i18next/react-i18next/issues/1880) and [#​1893](https://github.com/i18next/react-i18next/issues/1893) escaping cases).
### [`v17.0.10`](https://github.com/i18next/react-i18next/blob/HEAD/CHANGELOG.md#17010)
[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.9...v17.0.10)
- fix(warnings): the `useTranslation` and `Trans` "You will need to pass in an i18next instance" warnings now match the `useSSR` wording, mentioning the props/context alternatives and the most common unexplained cause at scale: duplicate react-i18next copies in monorepo setups. The `Trans` variant also referenced the internal `i18nextReactModule` name; it now points to the public `initReactI18next` API.
- feat(warnings): development-only warning (`SUSPENDED_WHILE_LOADING`, logged once) right before `useTranslation` suspends while translations are loading. With the default `useSuspense: true` and no `<Suspense>` boundary this previously surfaced as a blank screen or a cryptic React error; the warning now names both fixes (add a `<Suspense>` boundary or set `react.useSuspense: false`). No-op in production builds; the `process.env.NODE_ENV` check is wrapped so runtimes without a `process` global (raw ESM in the browser, some edge runtimes) stay silent instead of throwing.
- ci: weekly workflow typechecking the test suite against `@types/react@next` / `@types/react-dom@next`, so the next React major's type changes (like the React 18 `TFunctionResult`/children wave) surface before user reports.
### [`v17.0.9`](https://github.com/i18next/react-i18next/blob/HEAD/CHANGELOG.md#1709)
[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.8...v17.0.9)
- fix: allow TypeScript 7 in the optional `typescript` peer dependency range (`^5 || ^6 || ^7`). With `typescript@7.0.2` in a project, `npm install` failed with an `ERESOLVE` peer conflict. Fixes [#​1927](https://github.com/i18next/react-i18next/issues/1927), thanks [@​andikapradanaarif](https://github.com/andikapradanaarif).
- fix(types): `<Trans t={t} ns="ns" …>` with a `t` from `useTranslation(['ns'])` now typechecks under TypeScript 7. TS7 intersects the `Ns` inference candidates coming from the `t` prop (`readonly ['ns']`) and the `ns` prop (`'ns'`) into an unsatisfiable `'ns' & readonly ['ns']`, where TS6 resolved them. The `ns` prop on `TransProps`, `TransSelectorProps` and `IcuTransWithoutContextProps` now also accepts a single namespace out of an array-typed `Ns` (`Ns | (Ns extends readonly (infer S extends string)[] ? S : never)`) — which matches runtime behavior and is unchanged under TS5/TS6.

[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.7...v17.0.8)
- fix(types): `<Trans i18nKey={$ => ...}>` now typechecks under `enableSelector: 'strict'`. The `Trans` component's conditional type was gated on `_EnableSelector extends true | 'optimize'`, excluding `'strict'` and falling back to the legacy string-key signature. Runtime was already correct (it calls `keyFromSelector(i18nKey)` whenever `typeof i18nKey === 'function'`); this is a type-only fix that widens the conditional to include `'strict'`. Thanks [@​Faithfinder](https://github.com/Faithfinder) ([#​1921](https://github.com/i18next/react-i18next/pull/1921))
### [`v17.0.7`](https://github.com/i18next/react-i18next/blob/HEAD/CHANGELOG.md#1707)
[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.6...v17.0.7)
- feat: `useTranslation([nsA, nsB, ...])` now passes its full namespace list to `getFixedT` via the new `scopeNs` opt (requires `i18next` ≥ v26.0.10). This makes selector calls with a secondary-namespace prefix resolve correctly under default `nsMode`: `t($ => $.nsB.foo)` previously missed silently because the bound `ns` was the primary string only and i18next's selector rewrite needed an array. Resolution semantics are unchanged — plain `t('key')` lookups still stay isolated to the primary namespace by default; use `nsMode: 'fallback'` to opt into multi-ns fallback resolution as before. Fixes [i18next#2429](https://github.com/i18next/i18next/issues/2429) for `useTranslation`-based callers.
### [`v17.0.6`](https://github.com/i18next/react-i18next/blob/HEAD/CHANGELOG.md#1706)
[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.5...v17.0.6)
- fix: restore the v17 `nodesToString` output format consumed by `i18next-cli`'s extractor while still rendering [1919](https://github.com/i18next/react-i18next/issues/1919) correctly
- 17.0.5 fixed [1919](https://github.com/i18next/react-i18next/issues/1919) by changing what `nodesToString` produced, which inadvertently changed the extracted translation strings for keep-tags wrapping non-keep React elements
- The fix now lives in the renderer: indexed `<N>` placeholders nested inside a keep-tag are scoped to that tag's own original React children (matching kept tags by name and positional occurrence at each level), so the translation string format produced by `nodesToString` is unchanged
### [`v17.0.5`](https://github.com/i18next/react-i18next/blob/HEAD/CHANGELOG.md#1705)
[Compare Source](https://github.com/i18next/react-i18next/compare/v17.0.4...v17.0.5)
- fix: `<Trans />` no longer breaks child rendering when a kept HTML node (`transKeepBasicHtmlNodesFor`) wraps a non-keep React element [1919](https://github.com/i18next/react-i18next/issues/1919) — superseded by 17.0.6, which keeps the same runtime fix without changing the `nodesToString` output

What:
Closes #1231
And removes the need for testing-library/user-event#1283
Why:
testing-library/user-event#1283
How:
By tracking if we're already inside an
act, we can avoid wrapping it in a new one. At the same time, we can keep the wrapper around all events, which is an expectation using testing library'sconfigureChecklist:
docs site
Originally I was going to make this change over in user event, we have two PRs to do it, however, it's really a React and Preact concern. Changing it in User Event would affect everyone. Angular testing library already wraps all events for a different reason and so removing an event from that callback wrapper could be unexpected or breaking. I would guess this change is also needed in the Preact testing library repo as well.
