On some pages the entire page is highlighted when panning. This is partially solved with the fix for bug #83153, but many pages still have global event listeners making which node to highlight tricky. I will go with a solution of highlighting either links or focusable elements, OR the nearest enclosing inline element. This avoids highlighting blocks unless they are a link, form or otherwise supports focus.
