We are failing this test in web-animations/timing-model/timelines/update-and-send-events-replacement.html: promise_test(async t => { const div = createDiv(t); const animA = div.animate( { marginTop: '10px' }, { duration: 1, fill: 'forwards' } ); const animB = div.animate( { marginInlineStart: '20px' }, { duration: 1, fill: 'forwards' } ); await animA.finished; assert_equals(animA.replaceState, 'active'); assert_equals(animB.replaceState, 'active'); div.style.writingMode = 'vertical-rl'; assert_equals(animA.replaceState, 'active'); assert_equals(animB.replaceState, 'active'); await waitForNextFrame(); assert_equals(animA.replaceState, 'removed'); assert_equals(animB.replaceState, 'active'); }, 'Removes an animation by another animation using logical properties after updating the context'); We fail the second-to-last assertion because we fail to schedule an animation update after changing writing-mode and thus don't run the procedure to remove replaced animations.
