Title: Fix redraw zooming issue (bug 972532)

This is a definite hacky solution but seems to be the only thing that prevents the zooming that happens when the page is scrolled up when the keyboard is up. The keyboard lowering makes it zoom see https://bugzilla.mozilla.org/show_bug.cgi?id=976531 for details and videos that show the problem.
