Comment 2 Ryan Haddad 2023-03-29 08:54:45 PDT
This test has been flakily failing on macOS WK1 and iOS simulator since it was added with https://commits.webkit.org/262039@main

The image diff shows that the test is expecting a red square on a white background but the red square is missing.

Side note: red generally shouldn't be used to indicate success in tests, https://www.w3.org/Style/CSS/Test/guidelines.html
