The TAO tests at https://github.com/w3c/web-platform-tests/blob/master/resource-timing/resources/iframe_TAO_match_wildcard.html are failing because the entry inside the same-origin iframe doesn't appear in its performance timeline. This is currently blocking https://bugs.webkit.org/show_bug.cgi?id=184627 from being testable.
This specific test no longer exists, but this got fixed as part of bug 226678.
