           Summary: REGRESSION (260129 at main): [ macOS wk1 ] 67+ tests are
                    a consistent failure

          Hardware: Unspecified
                OS: Unspecified

Description:
At least 67+ tests are consistently failing after landing 260129 at main.
It is difficult to inspect each test as a group on the WebKit Results Database due to the lag time and urgency of many tests broken by the commit 260129 at main.
I spot-checked a couple of tests to confirm.

This seems to be affecting the following kinds of tests and possibly others:
http/tests/referrer-policy-anchor
http/tests/referrer-policy-iframe
http/tests/referrer-policy-img
imported/w3c/web-platform-tests/html/dom/render-blocking
imported/w3c/web-platform-tests/remote-playback

This issue can be bisected to 260129 at main using command:
run-webkit-tests --release --iterations=1 -1  imported/w3c/web-platform-tests/html/dom/render-blocking/parser-blocking-script.tentative.html

Test Run: 
https://build.webkit.org/#/builders/705/builds/1206

Results:
