Theme Installer: Preview should be scrollable on iPad and Kindle Fire

Related to #20805. We've added techniques for smoothly scrolling iframes when they're the only frame on the page, but the theme installer still uses the overlay technique.
We may be able to iron this out in a similar fashion. Given that the old installer also used an overlay technique, this is not a regression.
