Test addition (253230 at main): [ macOS ]  http/tests/media/fairplay/fps-mse-unmuxed-multiple-keys.html  is a flaky/consistent failure/image failure/timeout/crash

Description:
http/tests/media/fairplay/fps-mse-unmuxed-multiple-keys.html 

This test was added at 253230 at main and has been a flaky failure since being added on macOS arm64.  The EVENT(updateend) is expected after the licenseResponse and session.update() are resolved instead of before.

Reproduction steps:
I can reproduce this on 254254 at main ToT.
