Bug 1992169 [wpt PR 55172] - CV: Avoid c-v applying to inline pseudo elements, a=testonly
Automatic update from web-platform-tests
CV: Avoid c-v applying to inline pseudo elements
When we style elements, we call DidStyleSelf which may unlock
the element due to missing constraints (containment, inlines).
However, when we initially create a pseudo element, it goes
through a different path which misses this call. This means
we can end up with c-v locked inline elements which causes problems
down the line.
This patch fixes this by calling DidStyleSelf on newly created
and styled pseudo elements.
