Description:
fast/images/animated-heics-draw.html

The first failure I saw on the dashboard was on 11/4/2022 at 256337@main.

This issue can be bisected to 251289@main using the command: 
run-webkit-tests --debug --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --iterations 50 -f --no-retry fast/images/animated-heics-draw.html

Result: 
Regressions: Unexpected timeouts (1)
  fast/images/animated-heics-draw.html [ Timeout ]

After landing 256803@main the test is still a consistent timeout on Ventura.

[Karl Rackler]

Current history shows test consistently passing.

Re-opening.  This was mistakenly closed, with the issue persisting due to a mixup on the test spot check.

This flaky crash can be bisected to 256803@main using the command: 
run-webkit-tests --debug --iterations 2000 --debug-rwt-logging --no-retry --force --no-build -f fast/images/animated-heics-verify.html

The above can also reproduce the consistent timeout.
