…rom Flow to TypeScript
WalkthroughThe pull request adds a Draft.js mention selector with contact suggestions, immutable mention entities, optional video timestamps, validation, serialization, Flow and TypeScript exports, and expanded TypeScript-compatible tests. ChangesMention and timestamp selector
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: ⚪ Minimal · up to This PR migrates the mention selector to TypeScript while preserving its public contract and removing an unused editor prop; the reported 97 tests, TypeScript lint, and Flow checks pass, and no actionable merge-blocking risk remains.

addMentionacceptsnullbut does not handle it.The signature declares
activeMention: Mention | null. Line 78 falls back to{}, sostartandendbecomeundefined. Lines 86-87 then passundefinedoffsets intoselectionState.merge, which produces an invalid selection instead of a clear failure.The Flow original had the same behavior with an untyped parameter. The new signature makes the unsafe path explicit, so guard it.
