There’s no way to display things on top of a BrowserView, so we’ll
either need to insert these directly into the page (which means they’ll
be affected by the displayed page’s CSS and might not render
correctly), or we would need to show the blurred preview image during a
swipe gesture (which looks bad,  although it might be better if we
start capturing preview images more frequently)
