Jelle Raaijmakers 2998049fe9 LibWeb: Implement the unreachable scrollable overflow
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).
