Fullscreen not working right on safari 8.0.5

[billgsm]

Although safari 8.0.5 supports fullscreen feature, it's not woking "well".
When I trigger the fullscreen, the screen gets dark but the video moves up to the right up corner and doesn't get resized whatsoever.
When I hit escape button I exit the (buggy) fullscreen mode to the normal mode.
PS: Fullscreen works fine on both chrome, firefox and IE11

Can you fix that please?
