-- JS
  var currentPlayer = document.getElementById("brightplayer-video");
                    
                    var textTracks = currentPlayer.textTracks; // one for each track element

// If track element doesn't exist, add it the first time this is called...
                    if(textTracks.length == 0) { 
                        var track = currentPlayer.addTextTrack("captions", "English", "en");

                        track.addCue(new VTTCue(0, 2, "[Test]"));
                        track.addCue(new VTTCue(4, 7, "This blade has a dark past."));
                        track.addCue(new VTTCue(9, 11, "It has shed much innocent blood."));
                    }
                    else {
// if track already exists, clear out the cues to reload with new cues....
                        var currentTracks = currentPlayer.textTracks; // one for each track element
                        var textTrack = currentTracks[0]; // corresponds to the first track element
                        var cues = textTrack.cues;
                        for (var i = cues.length; i >= 0; i--) {
                            textTrack.removeCue(cues[i]); // error occurs here
                        }
                        textTrack.addCue(new VTTCue(0, 2, "[Test2]"));
                        textTrack.addCue(new VTTCue(4, 7, "This blade has a dark past.2"));
                        textTrack.addCue(new VTTCue(9, 11, "It has shed much innocent blood.2"));
                    }

What is the expected result?
The cues would be removed.

What happens instead of that?
Exception : Failed to execute 'removeCue' on 'TextTrack': parameter 1 is not of type 'TextTrackCue'.
