Created attachment 405088 [details] test In the attached test, hover the spinner. This should change the timing function, but the same KeyframeEffect persists, and KeyframeEffect::computeSomeKeyframesUseStepsTimingFunction() is never called.

KeyframeEffect::animationDidChangeTimingProperties() needs to call computeSomeKeyframesUseStepsTimingFunction().

The attached test works fine for me on a ToT build on macOS. When the spinner is not hovered, it progresses very slowly step-by-step while when it's hovered it has a linear animation. I didn't see any obvious difference between its behavior on a ToT build and recent Firefox and Chrome.
