Bug 277933 – REGRESSION (iOS 18): 5 WPT CSS layout tests are constantly failing (ImageOnlyFailure).

• Status: RESOLVED
• Resolution: FIXED
• Component: CSS

[Ben Schwartz]

The following tests are constantly failing on iOS 18:

imported/w3c/web-platform-tests/css/css-content/quotes-025.html [ ImageOnlyFailure ]
imported/w3c/web-platform-tests/css/css-content/quotes-026.html [ ImageOnlyFailure ]
imported/w3c/web-platform-tests/css/css-content/quotes-027.html [ ImageOnlyFailure ]
imported/w3c/web-platform-tests/css/css-text/text-transform/text-transform-fullwidth-004.xht [ ImageOnlyFailure ]
imported/w3c/web-platform-tests/css/css-text/text-transform/text-transform-fullwidth-005.xht [ ImageOnlyFailure ]

HISTORY:

None, as we don't test iOS 18 in WebKit CI yet.

REPRODUCIBILITY:

I was able to reproduce this issue on the latest iOS 18 simulator (18.0/arm64) ToT using the following command:

run-webkit-tests --ios-simulator --test-list /path/to/tests.txt

...where tests.txt contains the list of tests above.

I found another test that seems to be affected in the same way:

fast/text/text-underline-position-under.html

Will set test expectations for this test as well.
