This may have slipped by our test suite because these flex-minimum-height-flex-items-XXX.html tests are marked [ImageOnlyFailure] in TestExpectations: 023 029 013 015

After looking a little further into this, it looks like the test changed to match Chrome's behavior in Oct 2021, 9 months after r273955 The commit message for the WPT test (https://github.com/web-platform-tests/wpt/commit/2c83d2e8d545706b565dc6e3dcf77daa77eb5e96) indicates that the behavior of Chrome, FF, and WebKit was out of spec according to the discussion here: https://github.com/w3c/csswg-drafts/issues/6693 When running Safari against that revision and the test as it existed in 03/2021 it looks like the revision did cause the test to pass but the interpretation of the spec may have changed. I'll look more closely at the csswg discussion.
