Bug 1381420 - A crash test that has an element is not restyled but has reconstruct frame damage during flushing throttled animations. r?emilio
The details element, which is a sibling of an animating element, is checked
whether the element needs to be processed in a post traversal for throttled
animation flush because the parent element has animation-only dirty bit (i.e.
the parent element is a common ancestor of the animating element and the
details element). Also at the moment of the check the details element has
reconstruct frame damage because 'open' attribute is changed. Thus in the check
the details element was not restyled but had reconstruct frame damage.
