This test has a render blocking element that prevents pagereveal from being fired, and then navigates to a new page. The test is expecting the navigation to happen without the pagereveal event being sent, so no cross-document view transition happens. With WebKit, initiating the navigation results in any pending fetch requests being cancelled, which removes the render blocking. Pagereveal then happens before we commit the navigation (and fire pageswap), so we get a VT and the test fails.

My reading of this spec makes me think this is expected: https://html.spec.whatwg.org/multipage/webappapis.html#queue-a-global-task
