Steps to reproduce:
1. Upload a video
2. Click on the eye icon for the preview of the video, after it is processed.
3. Seek to the middle of the video and make sure the video is paused
4. Switch to the editor.
The scrubber in the Waveform timeline is at the beginning of the video, but when you press play it plays at the time that you set in preview.
The scrubber would point to the real play time.
Workaround (if any):
Press play, than the scrubber jumps to the right time, or do not pause the video in the review player.
