See https://github.com/w3c/web-platform-tests/pull/9390 for tests.
Looks like we're failing all the checks at: http://w3c-test.org/html/browsers/windows/auxiliary-browsing-contexts/opener-setter.window.html
The tests seem to expect window.opener to no longer be replaceable. This seems like risky behavior change and I am not sure we want to do this. I had aligned WebKit with the spec via Bug 181505 already (to fix issues with Gmail).
Chris, I assume per https://github.com/whatwg/html/pull/3448#issuecomment-363208579 you now agree with this bug, right?

Safari 15.6 on macOS 12.5 pass all 7 test cases from attached test case URL: http://w3c-test.org/html/browsers/windows/auxiliary-browsing-contexts/opener-setter.window.html It matches with all other browsers (Chrome Canary 106 and Firefox Nightly 105). Is something else needed here? Thanks!
Looks like config changed to me.
