This is because InspectorDOMAgent::m_document is not correctly updated when the main resource is 'multipart/x-mixed-replace'. 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.
