Failed to execute 'addCue' on 'TextTrack': parameter 1 is not of type 'TextTrackCue' #17

Hi,

When a user stops to cast an HLS stream with captions, Chrome raises an exception:

Uncaught TypeError: Failed to execute 'addCue' on 'TextTrack': parameter 1 is not of type 'TextTrackCue'.

It's very easy to repeat here: http://www.w3schools.com/code/tryit.asp?filename=F09KO2XJN00D

Steps:

  1. start playback
  2. start casting, wait for playback on Chromecast
  3. stop casting
  4. notice an exception in Chrome console

As a result player fails to switch from cast tech back to html5 tech. Any help is appreciated.
