This test was an ImageOnlyFailure [so far] only once at 270640@main on macOS Sonoma (on arm64), wk2 release.

HISTORY:

https://results.webkit.org/?suite=layout-tests&test=fast%2Fcss%2Fgradient-prefixed-unprefixed-toggle.html&platform=mac

IMAGE DIFF:

Attached.

REPRODUCIBILITY:

I was unable to reproduce this issue on macOS Sonoma (14.1, 23B74/arm64) ToT.

NOTE:

It appears the output from a previous test run (fast/css/getPropertyValue-returns-empty-on-missing-property.html) remained on the screen, which at least contributed to the failure, if not fully caused it.

I think we decided this was a repaint issue.

This looks very similar to the underlying cause of https://bugs.webkit.org/show_bug.cgi?id=273212, which was much easier to reproduce. For now, I'm going to dupe. If we get more data in the future, we can revisit this choice.
