    <thetext>imported/w3c/web-platform-tests/css/css-writing-modes/text-orientation-mixed-srl-016.xht is a flaky image diff on iOS release.


HISTORY:
https://results.webkit.org/?suite=layout-tests&amp;test=imported%2Fw3c%2Fweb-platform-tests%2Fcss%2Fcss-writing-modes%2Ftext-orientation-mixed-srl-016.xht&amp;platform=ios

IMAGES:
See attached.


REPRODUCTION:
I was able to reproduce this on iOS 26.3 release with the following:

run-webkit-tests --no-build --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=2000 --force -f --ios-simulator --release imported/w3c/web-platform-tests/css/css-writing-modes/text-orientation-mixed-srl-016.xht

I am going to mark expectations as imageOnlyFailure Pass while this pends investigation.</thetext>

    <thetext>This test is flaky on iOS due to small pixel inconsistencies across runs, adding retest-wait to relevant files allows renders to fully settle before screenshots are taken. Putting this up as a PR.</thetext>
