CrashTracer: [USER] com.apple.WebKit.WebContent at com.apple.WebCore: WebCore::ExtensionStyleSheets::pageUserSheet + 14 https://bugs.webkit.org/show_bug.cgi?id=165030 Reviewed by Darin Adler. Source/WebCore: We failed to reset the style scope when an element was moved to a different document. This could lead to having dangling document pointers in style scope and style resolver. Test: fast/shadow-dom/shadow-host-move-to-different-document.html * dom/ShadowRoot.cpp: (WebCore::ShadowRoot::didMoveToNewDocument): Reset style scope. * dom/ShadowRoot.h: * style/StyleScope.cpp: (WebCore::Style::Scope::resolver): Some more assertions. * style/StyleScope.h: (WebCore::Style::Scope::document): LayoutTests: * fast/shadow-dom/shadow-host-move-to-different-document-expected.html: Added. * fast/shadow-dom/shadow-host-move-to-different-document.html: Added.
