Wasn't Youtube limiting WebM Fullscreen to "Content View" Fullscreen as opposed to Flash Usage where it is true Fullscreen?

FWIW, I see no Difference in Google Chrome 11.0.672.0 <-> Fx 4 Trunk Behavior.

They override our "Full Screen" right-click context menu, and until the Full Screen API is supported in Firefox, there's no way for them to provide that via a button.
