WindowServer: Fix traversing modal stack

Browse source 
When walking the modal window stack upwards, we need to check if
the top modal window is still a descendant of the window that
the parent is blocked by. Fixes not all windows being brought to
the front when trying to active a parent in the middle of the
modal window stack.
