Right now we determine whether a property is set to "inherit" in a keyframe by doing a string comparison when the Web Animations API is used to set keyframes. However, the StyleRuleKeyframe created for the keyframe has StyleProperties where the value is parsed, it seems safer to check the CSSValue rather than do a string comparison here.
