http/tests/security/block-top-level-navigation-via-redirect-by-third-party-iframes.html is failing flakily with the following diff on macOS release post-commit bots

  -CONSOLE MESSAGE: Unsafe JavaScript attempt to initiate navigation for frame with URL
  'http://127.0.0.1:8000/security/block-top-level-navigation-via-redirect-by-third-party-iframes.html' from frame with URL
  'http://localhost:8000/security/resources/navigate-top-level-frame-to-failure-page-via-redirect.html'. The frame attempting navigation of the top-level
  window is cross-origin or untrusted and the user has never interacted with the frame.
   Test blocking of suspicious top-level navigations by a third-party iframe (same-site but redirects to a different site)

   On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".

See https://results.webkit.org/?suite=layout-tests&test=http%2Ftests%2Fsecurity%2Fblock-top-level-navigation-via-redirect-by-third-party-iframes.html&flavor=site-isolation

https://commits.webkit.org/311805@main attempted to fix this test and added a 1000ms timer
among other changes to fix this test.

That commit was successful in fixing the iOS bots, but macOS bots are still flaky with the above diff sometimes.
