With same-site BFCache enabled every navigation can now potentially be served via the BFCache. To support this internally a new top-level RenderFrame object may be created for each new navigation. As a result, OnBrowserCreated may now be called multiple times with the same browser ID in a given renderer process (a behavior previously only seen with cross-site navigations and different renderer processes). BFCache navigations do not trigger the same Chromium notifications as a normal load. To avoid breaking CEF API usage expectations we now synthetically generate the load-related callbacks that would otherwise be missing (OnLoadingStateChange with isLoading=true, OnLoadStart, OnLoadEnd). The |httpStatusCode| argument to OnLoadEnd will be 0 in this case. To test: - Run `FrameHandlerTest.*:MessageRouterTest.*:NavigationTest.*` - Run `NavigationTest.LoadSameOriginLoadURL` for OnBrowserCreated behavior. - Run `NavigationTest.History` for load-related callback behavior. |
