In hover to select mode, auto scrolling should be disabled so elements aren't jumping around the page as they're trying to be selected and the inspected page should be focused when select mode is started to match Firebug.
Lets just disable scrolling for all highlights. We have gotten requests to remove it since it is annoying when the page moves when you are hovering the DOM tree. Maybe we want a modifier key?
It would be nice, if you disabled scrolling (which I think you should) if, when the highlighted node was off-screen, an arrow pointing in its general direction would show up.
