Stale IntersectionObserver entries abort callbacks for active observers

Description

The IntersectionObserver manager explicitly tolerates stale native entries when an observer is disconnected between commit and mount. However, encountering one missing registration returns from the entire notification pass, dropping every later entry and callback in the same native batch, including entries for still-active observers.

Expected behavior

A stale entry for a disconnected observer should be ignored while notification continues for all active observers in the batch, matching the equivalent ResizeObserver handling.

Inizia dal passaggio di notifica del gestore di IntersectionObserver e confronta la gestione delle voci obsolete con la gestione equivalente di ResizeObserver menzionata nell’issue. Riproduci o esamina un batch contenente un observer disconnesso seguito da observer attivi, quindi verifica che le voci obsolete vengano ignorate e che i callback attivi successivi continuino a essere eseguiti.
