示例1: StringOrDictionary
TEST(TreeScopeTest, CommonAncestorOfTreesAtDifferentDepths) {
// document
// / \ : Common ancestor is document.
// Y B
// /
// A
Document* document = Document::create();
Element* html = document->createElement("html", StringOrDictionary());
document->appendChild(html);
Element* head = document->createElement("head", StringOrDictionary());
html->appendChild(head);
Element* body = document->createElement("body", StringOrDictionary());
html->appendChild(body);
ShadowRoot* shadowRootY =
head->createShadowRootInternal(ShadowRootType::V0, ASSERT_NO_EXCEPTION);
ShadowRoot* shadowRootB =
