imported/w3c/web-platform-tests/webvtt/rendering/cues-with-video/processing-model/selectors/cue/white-space_pre.html is a constant image failure on macOS and iOS.


HISTORY:
https://results.webkit.org/?suite=layout-tests&test=imported%2Fw3c%2Fweb-platform-tests%2Fwebvtt%2Frendering%2Fcues-with-video%2Fprocessing-model%2Fselectors%2Fcue%2Fwhite-space_pre.html

REPRODUCTION:
I was able to reproduce this on macOS 26.4 release ToT with the following:

run-webkit-tests --no-build --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=5 --force --release imported/w3c/web-platform-tests/webvtt/rendering/cues-with-video/processing-model/selectors/cue/white-space_pre.htm

I am going to mark expectations as imageOnlyFailure while this pends investigation.
