This test, previously constantly crashing on wk2 debug and constantly failing on wk2 release, is now constantly failing on all Apple configurations.

REPRODUCIBILITY:

I was able to reproduce this issue on macOS Ventura (13.6, 22G120/arm64) ToT using the following command:

run-webkit-tests --debug --clobber-old-results --verbose imported/w3c/web-platform-tests/webcodecs/audio-encoder.https.any.html

REGRESSION:

I was able to bisect a regression point at 267963 at main (issue did not reproduce at 267962 at main). Changes at that point are directly related to this issue, and are likely what caused it.
