Unreviewed.

It was supposed to only change behavior when site isolation was on.
It broke the tests http/tests/inspector/target/provisional-load-cancels-previous-load.html
and TestWebKitAPI.ProcessSwap.QuickBackForwardNavigationWithPSON.
This fixes those two tests and restores existing behavior with site isolation off.
There is still work to do when site isolation is on.  A lot of work.
