Fix an issue with unset_boxes_in_subtree in layout_2020

Browse source 
If the root node of the subtree doesn't have any boxes to unset, we
should exit early instead of unsetting boxes on siblings of the root.
This eliminates an infinite loop in this method, since the siblings of
the root are not in the subtree.
