The first failure that I saw on the dashboard for Big Sur was 2/15/2022 at r289818, which handles a respond to protocol for RVItems but this does not appear relevant to causing this issue.  The first failure that I saw on the dashboard for Monterey was 3/17/2022 at r291422, but this does not appear relevant to causing this issue.  These tests seem to have been flaky since the start. 

REPRODUCTION STEPS
I can reproduce this on ToT r293531.

Command: 
run-webkit-tests --root -1 --clobber-old-results --iterations 250 --exit-after-n-crashes-or-timeouts 1 --no-retry-failures --force -f 

Result:
