Seeked to the current playback position.

Your if should use == LefButton (if that exists), or a comment to explain that 0 is the left button.
1 if (window.eventSender)
If you were a committer I would just r+ and you could fix this when landing. Since I don't think you are, please re-post with the two above fixes
