Description:
compositing/show-composited-iframe-on-back-button.html

Is a flaky image failure on Sonoma ToT and since bring-up.

This issue can be reproduced using the command: 
run-webkit-tests --release -f --clobber-old-results --exit-after-n-failures 1  --force  --child-processes=5 --iterations=50 -1  compositing/show-composited-iframe-on-back-button.html

This may need pixel tolerance.

I verified with Simon that, in this case, we will add pixel tolerance.
