Description Chris Dumez 2019-05-29 19:19:00 PDT 
Third-party extensions using WKWebView are unable to render anything because we do not get notified when the extension's visibility changes. Because we do not recognize the extension showing the WebView to be foreground, we do not take a process assertion on behalf of the child processes and they get suspended before they get a chance to render anything.
