Autoplay observations: controls stuck on, play button?

Hi, I've been playing with the new autoplay option. It works just as advertised, thanks. I have a couple of comments:

1. When autoplay is on, the controls are visible when the video starts playing, and they don't disappear. They only go away if you mouse over the video and back off.

2. The big play button while loading is sorta redundant. It'd be nice to have a spinner or something indicating that something's happening instead.

Thanks!
