  • Avoids timers overlapping in the LiveAnnouncer, which can happen if a new message is announced within 100ms of the previous one. This can be an issue if the screen reader started reading out the previous message and then gets interrupted by the new one.
  • Avoids leftover timers if the service is destroyed.
  • Fixes the reference to the _liveElement not being cleared after it's removed from the DOM, potentially leaving it in memory.
