Description Antoine Quint 2023-03-29 08:38:18 PDT

While we fixed a WPT test that tested override of transform animation using !important in bug 252481, there is a case that that patch did not cover. The case is when the !important value matches the 0% value of the animation, as would be the case where no 0% keyframe is specified.
