Could I please convince you to split the intended behavior change from all of the argument passing cleanup?

Seems quite unrelated

>  }

This creator being changed to return null is alarming. Does Safari still use this SPI? If so, they almost certainly don't null check the result?

We have to say this because of the virtual ness, but can't it be in the header?

Looks like this broke http/tests/navigation/window-open-redirect-and-remove-opener.html. It's hitting a debug assertion:

https://results.webkit.org/?suite=layout-tests&test=http%2Ftests%2Fnavigation%2Fwindow-open-redirect-and-remove-opener.html

https://webkit-test-results.webkit.org/dashboards/flakiness_dashboard.html#showAllRuns=true&tests=http%2Ftests%2Fnavigation%2Fwindow-open-redirect-and-remove-opener.html

[Truitt Savell]

I was able to reproduce the failure by running the test on r252492 but not r252491. 

reproduced with command:
run-webkit-tests http/tests/navigation/window-open-redirect-and-remove-opener.html --iterations 500 -f --debug --exit-after-n-crashes-or-timeouts 1

[Alex Christensen]

I'm looking into it.

https://trac.webkit.org/changeset/252601/webkit fixes the test.
