From the right corner, manually forward the Youtube video to its end for a few times. [Expected result]: - The Youtube video/audio is playing properly.

I see it jump between playing and paused on the controls.
I've looked into it and saw that the site invokes Pause=>Seek=>Play when it forwards. The issue happened where the site's call pattern becomes Pause => Seek => Play => (Pause => Play) * N, Chrome also has the same the phenomenon, but the Pause/Play will stop after 3~4 rounds then it continue the playing. For me, it seems somehow certain event dispatching sequence leads to the abnormal Pause/Play loop, need more time to figure this out ...
