This is required to be done in WR rather than Gecko since a backdrop
filter may exist in a child iframe display list but sample from a
backdrop root in a parent iframe (if the iframe has transparency
enabled). In this case the parent display list has no knowledge
that a backdrop filter primitive is present.
