Description:
imported/w3c/web-platform-tests/css/css-sizing/aspect-ratio/replaced-element-035.html

The first failure that I saw on the dashboard was on 4/15/2022 at 249678@main, but this does not appear relevant to causing this issue.  This test has been flaky for its entire history on the dashboard.

This test was imported on April 15 with https://commits.webkit.org/249676@main, so it has probably been flaky from the start.
