With reference to the comments from Hayato in bug https://bugs.webkit.org/show_bug.cgi?id=81102, "We should rename getElementInShadowTreeStack since it can return ShadowRoot, which is not Element. That is an unintentional usage that it can return ShadowRoot. So we should rename it to getNodeInShadowTreeStack."
