Description Justin Cohen 2019-04-15 13:41:40 PDT 
Steps:
- Enable content restrictions and set web content to 'allowed websites only' (e.g. disney.com)
- Visit disney.com
- Visit cnn.com


In WKWebView, I see WebKit print the following error:
 [ProcessSwapping] 0x117324160 - ProvisionalPageProxy::didFailProvisionalLoadForFrame: pageID = 2, frameID = 1, navigationID = 5

I see a didFailProvisionalNavigation callback, but no didFinishNavigation and I don't see the built in error page (You cannot browse this page at "cnn.com" because it is restricted.)  I still see disney.com

If I immediately load cnn.com in a new WKWebView, I do see the proper error page.

MobileSafari is also inconsistent.  If you visit cnn.com on a new page you see the correct restricted error.  If you visit disney.com first, you see (Safari cannot open the page.  The error was; "The URL was blocked by a content filter."

nit: Should probably be a const method.
