Created attachment 167688 [details] Testcase If we animate a CSS value using SVG and change the animation, the animated CSS value does not reset. In the attached testcase, opacity is animated to 0.5 and then the animation is changed so that 'x' is being animated, but the opacity remains at 0.5.

I don't see X animating at all. Still, Chrome and Firefox return opacity to 1.0, which Safari does not. There appears to be a bug of some kind here
