fast/images/decode-render-animated-image.html is a flaky failure on macOS release.
HISTORY:
https://results.webkit.org/?suite=layout-tests&test=fast%2Fimages%2Fdecode-render-animated-image.html
IMAGE URL:
https://build.webkit.org/results/Apple-Tahoe-Release-AppleSilicon-WK2-Tests/313164@main%20(3860)/fast/inline/blocks-in-inline-paint-order-diffs.html
IMAGES:
See attached.
REPRODUCTION:
I was able to reproduce this on macOS release 26.4 ToT with the following:
run-webkit-tests --no-build --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=1000 --force --release fast/images/decode-render-animated-image.html
I am going to mark expectations as pass imageOnlyFailure while this pends investigation.

Looks like a WEBKIT issue. Any "fix" in the test (adding retries, rAFs, sleeps between decode/drawImage) would be compensating for the exact guarantee that the two helpers are supposed to provide: decode() promise resolving means "next frame decoded & ready to paint," and the debug canvas drawing setting means "canvas shows that current frame."
