REPRODUCIBILITY:

I was able to reproduce this issue on macOS Ventura (13.5, 22G74/arm64) ToT using the following command:

run-webkit-tools --verbose --clobber-old-results --iterations 10 http/tests/contentextensions/main-resource-redirect-blocked.py http/tests/contentextensions/main-resource-redirect-error.html http/tests/contentextensions/block-everything-unless-domain.html http/tests/contentextensions/block-everything-unless-domain-iframe.html http/tests/contentextensions/block-everything-unless-domain-redirect.py

REGRESSION:

I was able to identify a potential regression point at 258473 at main. This issue did not reproduce before then, and changes at that point appear to be directly related to the issue.
