React Native: Precision Fixes Across the Stack

The root cause: the Hermes runtime and the Hermes compiler were being resolved from two different, unsynced sources — one live from the npm registry, one pinned locally. When those drift apart, apps crash on…
Similar precision fix from cipolleschi in PR 57964: VirtualizedList was mishandling zero-area layouts in horizontal lists, treating collapsed items as visible because viewability only checked the main axis. Now it tracks zero-area layouts explicitly and invalidates stale viewability updates. If you rely on…
And Alex Hunt's commit b74adf0 adds idle frame detection to the Performance timeline in React Native DevTools — synthesizing frame events when the gap between real frames exceeds one display refresh interval. It's detail-heavy work: dropping frames from before recording starts, sorting by timestamp to handle…
