Tested on Web 4.53.0 on PC Chrome, and on Android TV 8.13.2.23227 on SHIELD.
- Play a movie with external SRT en subtitle
- Note the subtitle offset you see with a stopwatch, and adjust accordingly (in tiny -50/+50ms increments); I tested with large offsets of ~10000ms.
- Note how it adjusts in realtime in the web client and sync up the subtitles
- Close the web video player or otherwise stop playback
- Resume that same movie
- BUG: notice how the subtitles are audibly offset again, the same as in step 2
- BUG: open the subtitle offset panel and notice how it displays the same offset from step 3.
- Repeat from 2 over and over, and the displayed offset just keeps growing while the audible offset resets when playback is stopped.
