Youtube video restarts at beginning resizing playback window.

[HAL]

Resizing any youtube video window causes the playback to start at beginning instead of where it is up to. This is the example video I was playing: ​https://www.youtube.com/watch?v=_Q2_YRpB4nQ I started web+ from a terminal to try and capture what was going on:

1. I started the video in default small window size.
2. I clicked the second button from right at bottom of window to resize to full.
3. I clicked again on same button to go back to small window.

Result: each time video restarted at beginning.
