imported/w3c/web-platform-tests/html/semantics/forms/the-select-element/customizable-select/select-base-appearance-computed-style.html is a constant text failure on macOS and iOS.

REPRODUCTION:
Reproduced on macOS 26.2 release ToT with the following:

run-webkit-tests --no-build --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=100 --force --release imported/w3c/web-platform-tests/html/semantics/forms/the-select-element/customizable-select/select-base-appearance-computed-style.html

I will mark expectations as failure while this pends investigation.
