WebKit has some unique failures for css/css-transitions/before-load-001.html. See https://wpt.fyi/results/css/css-transitions/before-load-001.html?label=experimental&label=master&aligned.
Odd, the test assertion passes but there is a timeout harness error!
I believe the delay set on the <img> in that test correctly delays the `load` event on the page by 100 seconds which causes the timeout.
I filed https://github.com/web-platform-tests/wpt/issues/34444 to discuss a change to the test.
No, the issue is that when we interrupt the <img> load the window load event isn't fired and rather still waits on that resource being loaded. So this test is really a loading bug.
I filed https://github.com/web-platform-tests/wpt/pull/34463 to modify the test and created one that specifically test for the window `load` delay and canceling long image loads.
I filed https://bugs.webkit.org/show_bug.cgi?id=241676 to deal with that issue.
