InspectorDOMAgent::m_document is updated only when FrameLoader::didCommitLoad() is executed. However, this happens exactly once per load. In the event of multipart replacing loads, this is not called for replacing loads, even though a new Document is created and set on the Frame. Radar: <rdar://problem/20594948>
