"Automatically hide scrollbars" doesn't work as expected

[stefanw1337]

Expected it to hide whenever there's no scrolling being done. But apparently it's always there whenever your mouse is on the page itself. If you go to the system taskbar or above to the address or tab bar, it goes away, instantly. No animations.

Would like it to be hidden whenever there's no scrolling being done, maybe after a user set delay, and with animation of it sliding out or fading out or something.
