Description: css3/background/background-repeat-space-content.html The first failure that I saw on the dashboard was 12/14/2021 at r287060, but this does not appear relevant to causing this issue. This test seems to have been flaky since the start.

r293447 didn't fix this?
For cases like this where the pixel differences are consistent, we should be using pixel tolerance to make them pass. Example: r288449
REPRODUCTION STEPS I can reproduce this on ToT (r293740). Command: run-webkit-tests --root 293740 --ios-simulator --exit-after-n-failures 1 --exit-after-n-crashes-or-timeouts 1 --details --debug-rwt-logging --pixel-tests --tolerance 0.10 --iterations 2000 --no-retry css3/background/background-repeat-space-content.html Result: Unexpected flakiness: image-only failures (1) css3/background/background-repeat-space-content.html [ ImageOnlyFailure Pass ]
How can this be flaky? We are just drawing the same circle.png in both actual and expected.
