When you bring up the media browser from the playback controls, and in the browser click on the currently open / playing video file, the playback position will be reset to the playback time when the video was last opened.
For example:
- Start playing a new video file a t=0s.
- After 5 minutes bring up the media browser.
- Click on the current video to get back.
I would expect the media browser to just close, but instead it closes and resets the playback time to t=0s.
While this may be by design -- and not strictly a bug -- I feel it's more intuitive that clicking on the currently open video in the browser just closes the browser, and doesn't try to reset the playback position.
