(WebCore::Element::invalidateForResumingQueryContainerResolution):
When restoring a page with the document element as a container from the
back-forward cache we may fail
to compute style for its descedants. This happens because the child invalidity
bit is not set and
we think the tree is clean.
Fix by setting the child invalidty bit when invalidating container queries for
resume.
