Looking at https://wpt.fyi/results/web-animations/interfaces/Animation/commitStyles.html?label=master&label=experimental&product=safari-220%20preview&product=safari-221%20preview, it appears that the test `web-animations/interfaces/Animation/commitStyles.html` got a bunch of new failures. I don't think something changed in WebKit but rather that the test change in https://github.com/web-platform-tests/wpt/commit/9bb63705b931d12d7f45d3f7248854ae0e115a64 caused this failure as Chrome started failing after that point as well. It's possible the spec changed and required the test changes as well.

Most likely this is the spec change in question: https://github.com/w3c/csswg-drafts/commit/aa2e02d2daee8d8eb146562f7a84d58f54f4b10c.
