Comment 3 for bug 1558792

I think this regressed with http://bazaar.launchpad.net/~oxide-developers/oxide/oxide.trunk/revision/1269, which is in 1.12 as well.

Basically when we rotate, the screen geometry updates occur a bit later than the webview geometry changes, and these don't trigger a resize of the webview compositor (which ignores the webview size in fullscreen mode, to work around a Flash bug)
