Description

dev:voicing type:bug

While working on related issue https://github.com/phetsims/number-play/issues/134#issuecomment-1032066605 and #65 I am seeing that the start and end event listeners frequenly fail to fire in iOS Safari. Causing an assertion in UtteranceQueue because the this.announcingUtteranceWrapper isn't cleared on the end event. And reading blocks do not highlight because the start event doesn't fire.

I tried re-introducing the safari workaround removed in https://github.com/phetsims/utterance-queue/issues/52, but it doesn't seem to fix it always. Though maybe it is better? It is hard to say, it seems to happen randomly.
