Description:
webanimations/accelerated-animation-slot-invalidation.html

The first failure that I saw on the dashboard for Big Sur wk2 was 3/2/2022 at r290756, but this does not appear relevant to causing this issue.  The first failure that I saw on the dashboard for Monterey was on 3/18/2022 at r291481.  This test seems to have been flaky since the start.  

REPRODUCTION STEPS
I can reproduce this on Tot ( r293441 ).

Command: 
run-webkit-tests --root 293441 --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --pixel-tests --tolerance 0.87 --iterations 2000 -f --no-retry

Result: 
Unexpected flakiness: image-only failures (1)
  webanimations/accelerated-animation-slot-invalidation.html [ Pass ImageOnlyFailure ]
