Unreviewed.

It caused assertions to hit when running SiteIsolation API tests
but the tests still passed after the assertions.
It also is occasionally hit in the layout test
http/tests/site-isolation/basic-iframe.html.

It was only needed for work that hasn't landed yet, so revert until
it cna be re-landed without any issues.
