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. 2055809 1 mattwoodrow 2024-08-27 20:14:21 -0700 My reading of this spec makes me think this is expected: https://html.spec.whatwg.org/multipage/webappapis.html#queue-a-global-task 2055810 2 mattwoodrow 2024-08-27 20:15:21 -0700 Wrong link, https://html.spec.whatwg.org/multipage/browsing-the-web.html#beginning-navigation:queue-a-global-task-3 2056375 3 webkit-bug-importer 2024-08-29 14:10:42 -0700 <rdar://problem/134965723> 2057708 4 mattwoodrow 2024-09-04 14:55:56 -0700 Pull request: https://github.com/WebKit/WebKit/pull/33144
