Allow :active-view-transition pseudo-classes after ::part().
Based on the discussion in
w3c/csswg-drafts#10806 and also in
w3c/csswg-drafts#10787, I think the conclusion
from #10806 applies to pseudo-classes as well, and I should reverse my
earlier decision to disallow the :active-view-transition pseudo-classes
after ::part(), even though today it is not possible for them to match.
This makes that change behind the CSSPartAllowsMoreSelectorsAfter flag
(status:experimental), which also contains other related changes.
This matches WebKit's current implementation of those pseudo-classes.
