Caption Track 'Delete Ripple' also deletes the same gap in video BUT not the audio

Steps to reproduce:
1. Cut then Delete section of Caption track and video track

2. Delete 'gap' in Caption track using 'Delete Ripple'.

 
Result: ... Caption Track 'Delete Ripple' also deletes the same gap in the video BUT not the audio

                 When moving audio track after the  Caption Track 'Delete Ripple', audio track is not synced to video track e.g., removing 2 seconds in  Caption Track using 'Delete Ripple' results in the associated audio track 'gap' being 2 seconds behind the video and caption tracks. Refer to screen shots.

When trying to 'Delete Ripple' the gap in audio track, the video track also moves 2 seconds 'left'. 

Problem is audio track becomes out of sync to Video track when using Caption Track using 'Delete Ripple'
Expected: ...Caption Track 'Delete Ripple' to only affect that track, not others. Audio to remain in sync with video track.
