[ Monterey Release ] webanimations/css-transition-retargeting-during-ready-promise.html is a flaky failure Description: webanimations/css-transition-retargeting-during-ready-promise.html The first failure that I saw on the dashboard was 3/17/2022 at r291466, which deals with smaller checkboxes that no longer vertically align with related text, but this does not appear relevant to causing this issue.
