View Manager::Update All Covering Widgets
While looking at some testcases, I found a bug where we fail to invalidate views correctly in some cases. Basically the code incorrectly assumes that a child widget completely covers the invalid region and therefore neglects to repaint the parent widget when it should. I will attach a patch. The testcase http://bugzilla.mozilla.org/showattachment.cgi?attach_id=6234 shows this; scrolling the gray DIV will not update the scrollbar thumb area correctly. (In particular, the area extending above the blue DIV is not updated correctly.)
OK ... now I'm ready for approval.
