Steps to reproduce

Visit:
http://demo.jwplayer.com/browser-examples/edge-tracks-change.html

This page has an event listener for textTracks.onchange. An alert should appear when this event is triggered.

1 - Begin video playback
2 - Change Closed captions

Expected behavior:
An alert should appear, displaying that the track has been changed.

Actual behavior:
No alert appears in Edge. (But does in Safari and Chrome)

This is needed by our video player to control the display of captions via our own control bar. It also appears to affect VTT captions and 608 embedded captions in HLS streams.

      I can confirm the bug in Edge 14.14382. In Firefox (Dev Edition 49), there’s no CC button for some reason, but it does work as intended in Chrome.

      I can confirm this bug me too, Firefox + Chrome raises the textTracks.onchange when clicking on cc button, and unfortunately not Edge.
