https://commits.webkit.org/270737@main added a new window.internals.isFullyActive(Document&) function — intended for tests where it’s necessary to ensure whether or not a particular document is fully active — and used that function to update (fix) the http/tests/security/xss-DENIED-script-inject-into-inactive-window2-pson.html test, which had been flaky since it was last updated in https://commits.webkit.org/269235@main.

And in that https://commits.webkit.org/269235@main change which caused the http/tests/security/xss-DENIED-script-inject-into-inactive-window2-pson.html test to become flaky, its companion tests at LayoutTests/http/tests/security/xss-DENIED-script-inject-into-inactive-window2.html and LayoutTests/http/tests/security/xss-DENIED-script-inject-into-inactive-window3.html had also been updated in the same way as the http/tests/security/xss-DENIED-script-inject-into-inactive-window2-pson.html had been before it was subsequently fixed.

And while those two other companion tests have not yet been flaky, we should also (re)update them to now use window.internals.isFullyActive(Document&) — in order to ensure they’re actually testing what they’re intended to be testing.
