Web Inspector: [SI] remoteFrameAccessError() assumes the lexical global
object wraps a LocalDOMWindow
https://bugs.webkit.org/show_bug.cgi?id=325814
rdar://188827090
Reviewed by Qianlang Chen.
JSObject::calculatedClassName uses the object's own realm as the lexical global
object.
For a RemoteDOMWindow, the resulting access check reaches
remoteFrameAccessError(), and
activeDOMWindow()'s downcast<LocalDOMWindow> fails. Use dynamicDowncast and
return an
empty message when the lexical global object isn't a local window.
