I think, though I am not entirely sure, that touch-adjustment is automatically performed in the frame that contains the midpoint, because it will be the frame receiving the event. Testing down into iframes contained in the result would help with the case where the hot-spot is in the top frame, but would probably still give problems when the hot-spot is in a lower frame.
