When navigating cross-origin a speculative RenderFrameHost (RFH) and CefFrameHostImpl is created in the browser process for the new frame object created in a new renderer process. The FrameAttached message then arrives for the speculative RFH, and as a consequence interfaces are bound between the new CefFrameHostImpl and the speculative RFH. If the pending navigation commits then the existing RFH will be replaced with the previously speculative RFH. Since interfaces are already bound we must keep the new CefFrameHostImpl. This means that frame objects (including for the main frame) will now always change after cross-origin navigation, and the old frame object will be invalidated. |
