Description Antoine Quint 2022-01-28 07:40:45 PST
css/motion/animation/offset-rotate-interpolation.html has 48 failures, we need to investigate and fix them.
Comment 1 Antoine Quint 2022-01-28 13:09:54 PST
WPT.fyi reports no such failure. There must be a sync issue on our end somehow.

Comment 2 Antoine Quint 2022-01-28 13:20:21 PST
So, this used to pass 100% but regressed with r287909, the fix for bug 218880.
Comment 3 Antoine Quint 2022-01-28 13:21:54 PST
This is the test that regressed:

      // Regression test for crbug.com/918430.
      test_interpolation({
        property: 'offset-rotate',
        from: '800deg',
        to: '900deg'
      }, [
        {at: -3.40282e+38, expect: '-3.40282e+38deg'},
      ]);
