LibWeb: Do paint-order traversal in Document::elements_from_point()

Browse source 
Elements are now collected according to paint order as spec says,
replacing the depth-first traversal of the paint tree with hit-testing
on each box.

This change resolves a FIXME in an existing test and adds a new
previously non-working test.
