TextTrackList: removeTrack event

The removetrack event is fired when a track is removed from a TextTrackList.

Using addEventListener():

const mediaElement = document.querySelector('video, audio');

mediaElement.textTracks.addEventListener('removetrack', (event) => {
  console.log(`Text track: ${event.track.label} removed`);
});

Using the onremovetrack event handler property:

const mediaElement = document.querySelector('video, audio');

mediaElement.textTracks.onremovetrack = (event) => {
  console.log(`Text track: ${event.track.label} removed`);
};
