Update state if WKNavigationDelegate responds with
WKNavigationActionPolicyCancel when RemoteFrames are being navigated
https://bugs.webkit.org/show_bug.cgi?id=296461
rdar://116203453
Reviewed by Alex Christensen.
After an investigation it was discovered that WKNavigationActionPolicyCancel
and WKNavigationResponsePolicyCancel both call didFailProvisionalNavigation()
or one of its variants, effectively cleaning up any cross process state
pollution, even with site isolation enabled. This confirms cleanup by adding an
assert on the existence of a provisional frame in createProvisionalFrame() and
having a test which would trigger the assert as a fail condition.
