Summary

• deduplicate React ancestor delivery for keyup, pointerdown/up, mousedown/up, dblclick, contextmenu, and native input/onInput at the shared ShadowRootHost boundary; preserve React onChange's existing single delivery
• add representative browser and nested-root evidence that component callbacks, React ancestors, native propagation, retargeting, and composed paths remain correct
• document the validated bubbling-event contract while retaining the known React capture-phase limitation

Release coordination

• Jira: https://youversion.atlassian.net/browse/YPE-6210
• docs(ui): reconcile shadow dom release contract #450 has merged; this PR now targets journey-to-the-shadow-dom
• actual Safari validation remains part of YPE-6214's final coordinated-release signoff

Verification

• pnpm lint
• pnpm typecheck
• pnpm build
• pnpm test
• focused Storybook browser tests in Chromium, Firefox, and Playwright WebKit
• pnpm test:ci-scripts
• pnpm changeset status --verbose
• git diff --check

Confidence Score: 5/5

The reviewed changes appear safe to merge; no actionable new issue was found.

Summary

The PR extends duplicate-event prevention at ShadowRootHost and adds browser stories for more event families and nested roots.

• More composed events reach React ancestors only once.

looks good. the five new families reach ancestors once, the tests fail without the fix, and stopPropagation still behaves. two non-blocking notes inline. nothing here should hold the merge.
