Replace cache-level optimistic updates (onMutate with temp IDs) with TQ v5's UI-level pattern (useMutationState + render-time derivation) for both issue-level and comment-level reaction toggles. The cache-level approach caused a race condition: temp IDs in the cache couldn't be deduplicated against real IDs from WS events, causing reaction counts to briefly flash incorrect values (e.g. 0→1→2→1). The UI pattern keeps the cache clean (always server-confirmed data) and derives optimistic state at render time from pending mutation variables. WS events safely update the cache without conflicting with temp data. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> |
