This test is a flaky image-only failure, so far only found on wk2 on macOS Ventura.

HISTORY:

https://results.webkit.org/api/results/layout-tests/fast%2Fforms%2Fborder-color-relayout.html

IMAGES URL:

https://build.webkit.org/results/Apple-Ventura-Release-AppleSilicon-WK2-Tests/267419%40main%20(4688)/fast/forms/border-color-relayout-diffs.html

REPRODUCIBILITY:

I was able to reproduce this bug on macOS Ventura (13.5, 22G74/arm64) using the following command (file attached):

run-webkit-tests --verbose --clobber-old-results --child-processes 1 --test-list /path/to/border-color-relayout-repro-list.txt

I was unable to reproduce on any version of macOS other than Ventura; however, the problem may exist on other macOS versions as the test is extremely flaky and is a relatively new regression.

REGRESSION:

I was unable to bisect a certain regression point. The earliest viewable failure on arm64 is 267411 at main, and the earliest on x86_64 is 267061 at main.
