I discovered a problem with the video size change. YouTube's progress "thumb" shows in the wrong position and when you click on the progress bar it also takes you to the wrong part. All their JavaScript appears to be built around the flexy container's intended size. I'm not sure the flexy container can be size-restricted with CSS after all.

It also may be because i made progress bar a little longer then intended for specific player size.
I'll look into problem later.

Hopefully solved in 0.5.3.
