Although it's just a theory for now, I would like to correct my previous
opinion. I think ::wrap should not count as parent because it is just
"pseudo" element and not real element. Just like ::before, ::after, and
::first-line, which never count as target-able elements when it comes to
using CSS child selector (>) and universal selector (*), ::wrap shouldn't
either. Therefore the old parent should still count as the direct parent no
matter how many ::wrap are generated between it and its direct child
elements, and child selector (>) should still work for its direct child
elements.
