useScrollBarWidthhook.Motivation and Context
The hook now uses a single module-level
resizelistener and cached measurement shared across all instances (viauseSyncExternalStore) instead of running its ownresizelistener, forced layout read andsetStateon every mount. Eliminates N duplicatecalculateScrollBarcalls where N is the number of components using the hook (e.g.Tooltip). No API changes.How has this been tested?
