Description Chris Needham 2020-01-16 03:03:29 PST
I have encountered a couple of issues with TextTrackCue enter and exit events in Safari:

- an enter event is fired if an active cue's startTime or endTime is changed
- an exit event is not fired if an active cue's startTime or endTime is changed such that it becomes no longer active.

I have documented the details of the tests I've done here: https://docs.google.com/document/d/1uq-wVjY3Lq6J3GLZb246-5smIjECxjZ4VqsY-gnIPek/edit

There's a demo page you can use to adjust cue start and end times interactively here: https://waveform.prototyping.bbc.co.uk/cue-events
