I don't think so?

Because DOM Arena helps if there is a node that is allocated/adopted this document before `OnStartRequest`, but I don't think that is always the case for XHR document?

Looks like `XMLHttpRequestMainThread::OnDataAvailable` would parse the XML and the create XML element, if this always get executed before the `OnStartRequest`, then DOM Arena helps here.
