No way to regression-test?

> Source/WebKit2/UIProcess/mac/WKFullScreenWindowController.mm:421
> +    _page->setTopContentInset(_savedTopContentInset);

Can we make this share some code? At least three lines of this code are identical to part of finishedEnterFullScreenAnimation: and all five lines are the same although for some reason they are not in the same order here and there.

We should make the two methods share as much as possible, to help us avoid bugs like this one.

This should go through PageClient and be implemented in WebViewImpl for Mac.

Tim told me (in person) to ignore the fact he said this.

Don't think you use this anymore?

Do you still need this? I don't think it's on by default, is it?
