Fullscreen Netflix Doesn't Work in My Extended Desktop via Safari (Lion)

Hello everyone, I was wondering if you could help me solve this problem. Since I updated to Lion and I view movies on Netflix, the Safari browser doesn't go into fullscreen mode when in the extended desktop. So basically when I put the browser window into the extended desktop and press the "full screen" button on the Netflix/Safari webpage, nothing happens. It works perfectly fine in Firefox.

Why is this? Is it a bug?
