I believe these tests are flaky. I have made a PR to improve it a while ago. I should probably get those improvement landed sometime.

STP 96 has enabled user agent UI for WebAuthn, which could cause crashes. This could be the reason why webauthn is 0 all the time.

One thing that surprised me is that the release blog post[0] mentioned Web Animations being enabled by default, but we see no differences in the test diff for web-animations/. It's possible we enable some flag that turned on Web Animations already, but I can't see it obviously in our safari setup[1].
