[Site Isolation]
http/tests/contentextensions/block-everything-unless-domain.html fails
https://bugs.webkit.org/show_bug.cgi?id=313134
Reviewed by Megan Gardner.
When site isolation triggers a process swap for a navigation, the new
WebProcess logs
the content blocker console message via WebChromeClient::addMessageToConsole.
This IPC
arrives at ProvisionalPageProxy::didReceiveMessage(), which only forwards a
specific
allowed list of messages to the main WebPageProxy.
AddMessageToConsoleForTesting is
not in that list, so it hits the fallback at line 856 and is silently dropped.
Fixed the test by adding AddMessageToConsoleForTesting to the allowed list of
IPCs
that get forwarded in ProvisionalPageProxy::didReceiveMessage().
