Description Hayato Ito 2012-07-20 00:17:36 PDT 
When a last child node is an insertion point which does not have distributed nodes nor fallback elements, ComposedShadowTreeWalker::lastChild should ignore such a insertion point.
Currently, walker.get() wrongly returns null after walker.lastChild() is called in such case.
