fix: #536 keystrokes typed in the composer never reach host-page hotkeys - #538
Conversation
Composed key events cross the shadow boundary, so a host page sees the retargeted target as the widget's shadow host element, not an input. Every docs-site "is the user typing in a field?" guard therefore fails and the site's global "/" search hotkey fires mid-sentence. The widget's own keyboard handling all lives at the host document (Solid event delegation, zag dismissable layers, the anchored listbox forwarding a synthetic event to its hidden input), so the boundary is the document, not the shadow host: a bubble-phase document listener stops keyboard events that originate from an editable inside the widget shadow root. Every document listener still runs; only the host page's window-level hotkeys are cut off. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
📝 WalkthroughWalkthroughThe embed widget now stops keyboard events from editable elements inside its shadow root before they reach host-page hotkeys. Mount teardown removes the listeners. An end-to-end test verifies composer and host-page slash-key behavior. ChangesWidget keyboard isolation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change prevents composer keystrokes from reaching host-page window hotkeys, but the new integration test may leak browser contexts and increase CI resource use, while the release note overstates the isolation boundary. Merge should wait for these bounded issues to be corrected. Sequence Diagram(s)sequenceDiagram

Describe the isolation boundary accurately.
The guard runs on document, not on the shadow host. It prevents propagation to window, but host-page handlers registered directly on document can still receive the event. The current text promises that all host-page hotkeys no longer trigger.

Create the widget page with browser.newPage().
The page fixture does not follow the repository rule for widget integration tests. Create the page with browser.newPage() and close it in teardown to prevent context leaks and CPU or memory spikes.

Closes #536.
Mechanism
Key events are
composed: true, so they cross the shadow boundary and the host page seesevent.targetretargeted to the widget's shadow host element — never an input. Every docs-site "ignore keystrokes while the user is typing in a field" guard (VitePress, Algolia DocSearch, Starlight — all the sameisEditingContent(event)shape) therefore fails, and the site's global/search hotkey fires mid-sentence: the search modal opens, focus leaves the composer, and the rest of the prompt interleaves.Why the boundary is the document, not the shadow host
The obvious fix —
stopPropagation()on the shadow host — breaks the widget. Everything the widget uses for keyboard handling lives at the host document:keydown/keyuptodocument(delegateEvents), so every JSXonKeyDownin the widget is a document listener;AnchoredListbox.handleKeyDownre-dispatches a syntheticKeyboardEventonto a hidden<input>inside the shadow root and relies on it bubbling to Ark's document-delegated handler.Stopping at the shadow host cut all of those off. Verified: it turned the composer trigger menu dead — ArrowDown/ArrowUp no longer moved the highlight (3 failures in
composer-trigger-menu.it.test.ts, green on the same commit without the change).So the guard sits on
documentin the bubble phase.stopPropagation()there does not affect other listeners ondocument— order-independently, every widget handler still runs — it only cuts the event off before it reacheswindow, which is where host-page global hotkeys live.Scope: only events whose
composedPath()[0]is anINPUT/TEXTAREA/SELECTorisContentEditableelement contained in the widget's shadow root. Keys pressed with focus on the host page are untouched, host-page inputs are untouched, and the guard is torn down with the widget inmountImpl's teardown.Known limit, called out deliberately rather than papered over: a host page that binds its hotkey directly on
document(rather thanwindow) still sees the event. Cutting those off needsstopImmediatePropagation, which would kill the widget's own document-level handlers. The big offenders (VitePress, DocSearch, Starlight) all bind onwindow.Test evidence
New IT
packages/embed/tests/e2e/host-hotkey-isolation.it.test.tsserves a host page carrying VitePress's exact/guard (target-tagName check,preventDefault, marks a live region) and drives the real widget:run tests in lib/utilstyped into the composer — the hotkey must not fire, and the text must survive intact./pressed with focus on the host page — the hotkey must still fire.Against unfixed code, (1) failed exactly on the reported symptom:
while (2) passed. Both green after the fix.
