SSIA. While going through IDL files (track etc.), I noticed that we have few usages of 'item()', which based on discussion with Chris seems to be more 'back compatible' but it is better to align with Blink and spec and remove the usage. So this is bug to remove them from following files: 'getter AudioTrack item(unsigned long index);' <- In 'AudioTrackList.idl'. 'getter TextTrackCue item(unsigned long index);' <- In 'TextTrackCueList.idl'. 'getter TextTrack item(unsigned long index);' <- In 'TextTrackList.idl'. 'getter VideoTrack item(unsigned long index);' <- In 'VideoTrackList.idl'. Just wanted to raise the bug to track it. Thanks!
