However WebView::close() no longer crashes. close() is never called in MojoShell since mojo can't shutdown yet. I tried closing the existing WebView and replacing it but somehow that caused it to only draw red. After a while of looking at this with abarth we decided to just load into the same WebView for now. Eventually we should do something smarter where we start the provisional load and only replace the webview once the new one is ready, but that's a later CL.
