fix: let host-app touches through when the survey has no overlay [ENG-3157] - #87

Navigate logical layers of code changes, visualize relationships, and explore their blast radius. WalkthroughThe Android library adds a JavaScript event for survey card rectangles and passes nullable rectangle data through the native callback path. It resolves survey and workspace overlay settings, then displays surveys as dialogs or in passthrough mode. In passthrough mode, the reported card rectangle configures touch routing, and the layout adjusts its bottom padding for keyboard insets. Instrumented tests cover rectangle decoding, touch regions, touch routing, keyboard calculations, and overlay resolution. Priority: ➖ Normal Merge Risk: 🟡 Moderate · up to Repeated survey triggers can display overlapping surveys before the first presentation completes.

- Around line 350-351: Update the duplicate guard in show(manager, id) to
reserve the presentation for that FragmentManager before enqueueing either
presentation path, so a second call is rejected while the first transaction is
pending. Clear the reservation when the transaction fails or the survey is
removed, and add a regression test that calls show twice before pending
transactions execute.

What & why
Was: a survey with
overlay: nonepainted nothing over the host app but swallowed every touch, so the app looked frozen until it closed.noneis the default overlay.Now: only the survey card takes touches; everything else reaches the host app. Light and dark overlays still block, as before.
Where to look
webview/FormbricksFragment.kt:show()picks the path;attachToHostContentplaces the view.webview/SurveyPassthroughLayout.kt: the touch decision and keyboard padding.webview/SurveyTouchRegion.kt: the three states (no rect yet / card / no card).How it works, and behaviour changes worth checking
The survey sat in a full-screen
BottomSheetDialogFragment. A dialog is its own window, and Android picks the window by bounds before any view sees the touch, so no amount of transparency lets a touch through. Foroverlay: nonethe same fragment now runs without a dialog: its view goes into the host Activity's content, wrapped in a layout that declines touch-downs outside the card rect the renderer reports. The parent then offers the touch to the host's own content underneath.light/darkkeep the dialog, since their backdrop is meant to block.track()again;show()now skips while a survey fragment is showing.isShowingSurveyis write-only on Android, so this checks the fragment manager instead.android.R.id.content, so a host that passed a child manager does not hit "No view found for id".SurveyOverlay.resolve, so they cannot disagree.Coverage
overlay: none: host usable beside the card, card inside, nothing left after closeoverlay: light: bottom-sheet dialog unchanged, host blockedshowruns twice in one turnSkipping survey … already showing; unit (mutation):aSecondShowInTheSameTurnDoesNotStackASecondSurvey,FormbricksFragment.kt:375commitNow→commitSurveyPassthroughInstrumentedTest, drop the guard atSurveyPassthroughLayout.kt:40SurveyTouchRegion.kt:77→Everything,Survey.kt:64swap operands,SurveyPassthroughLayout.kt:83dropmaxRerun:

WebAppCallback.onCardRectChangeis defaulted, so implementors still compile.
