    <thetext>imported/w3c/web-platform-tests/css/css-sizing/aspect-ratio/replaced-element-035.html is a flaky failure on macOS WK2 queues. It is known to be flaky on macOS WK1, but the diff is not the same.

Image diffs showing that the test expects 00:00 but is seeing -00:00

    <thetext>Though there were some intermittent failures before, the flakiness on macOS WK2 is very apparent as of 3/21/2023.

cc&apos;ing Antoine as there was a media controls related change at that time (commits.webkit.org/261912@main), but it isn&apos;t obvious to me that it is related.</thetext>

    <thetext>We end up in a layout state where we display the remaining duration time label instead of the remaining time label and this is due to some odd layout code in TimeControl. I believe the issue is that the metrics computed with _performIdealLayout() relies on the visibility state of the elapsed time label, I&apos;m looking into cleaning things up there.</thetext>
