We have logic that detects when an iframe is overlapped, and then calls -setCopiesOnScroll:NO on the iframe's content view so that AppKit does a full repaint of the view when it gets scrolled. However, this logic only works for a single level of iframe. Nested iframes are not told that they are overlapped.
