Whenever we end up with a scrollable overflow rect that goes beyond either of its axes (i.e. the rect has a negative X or Y position relative to its parent's absolute padding box position), we need to clip that rect to prevent going into the "unreachable scrollable overflow". This fixes the horizontal scrolling on https://ladybird.org (gets more pronounced if you make the window very narrow).
