[css-conditional-5] @container: originating element of ::part() is the
element itself
rdar://183154183
https://bugs.webkit.org/show_bug.cgi?id=320208
Reviewed by Antti Koivisto and Tim Nguyen.
When determining the container element to query against, if the element
is from a ::part() pseudo-element, ContainerQueryEvaluator::selectContainer
picks element->assignedSlot() as the originating element. This seems wrong,
as in this case, the originating element is the element itself.
