imported/w3c/web-platform-tests/html/semantics/embedded-content/media-elements/preserves-pitch.html is a flaky text failure on macOS.

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

run-webkit-tests --no-retry --no-show-results --exit-after-n-failures=1 --expect-pass --iterations=500 --force -f --clobber-old-results --debug imported/w3c/web-platform-tests/html/semantics/embedded-content/media-elements/preserves-pitch.html

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