Nate Chapin c89c906507 Bug 1824039 [wpt PR 39152] - NavigationAPI: navigateEvent.commit() and { commit: 'after-transition' }, a=testonly
Automatic update from web-platform-tests
NavigationAPI: navigateEvent.commit() and { commit: 'after-transition' }

Explainer: https://github.com/WICG/navigation-api#manual-commit
I2P: https://groups.google.com/a/chromium.org/g/blink-dev/c/Aef4fm1Wn18

This introduces a new `commit` option on navigateEvent.intercept().
When `commit` is set to 'after-transition', instead of immediately committing
the navigation when the NavigateEvent finishes dispatch, we defer the
commit until navigateEvent.commit() is called or just before
navigatesuccess fires (whichever comes first).
