As Ms2ger said, :first-child now matches elements without a parent
(technically, it matches elements without a parent and without a
previousElementSibling).
<https://www.w3.org/Style/CSS/Tracker/issues/317> is the issue that
led to the change, which was
<https://github.com/w3c/csswg-drafts/commit/d57fda06a4f0aebb598e3341a2153bd958c171bc>.
It seems to originate in feedback from bz, wondering why it doesn't
apply.
