Cue.text for vtt format parser strips out tags like TAG_VOICE "v" without setting it on the cue. This sets original markup with tags on the cue to allow extracting any tag in the application in 7548a3f.

I copied original source code for WebvttCueParser and Cue to make the change as the classes were final and could not be subclassed. Curious to know if there's a better way to handle this.

Could you report the issue in the media repository? Hopefully they can add needed APIs and we can remove copied classes in the future. If they agree that this is something they could add we could make a PR to their repo.

I'm reverting support for speaker info in VTT transcripts. I'm having issues including library class duplicates in the release apk in minifyReleaseWithR8 task.

Also, including library class duplicates may cause issues in code maintenance. I'll try supporting speaker info in VTT transcripts separately.
