Original issue's description:
> Make createWindow (mostly) work with OOPIF
> 
> If a RemoteFrame is targeted by window.open(), we correctly plumb the navigation out of blink.
> 
> We no longer assume that ChromeClient::createWindow will return a Page with a local main frame. However, there are a several places where we wouldn't have the plumbing to set the correct state even if a Page with a remote main frame was ever returned.
