Created attachment 459751 [details] bug demo According to https://developer.mozilla.org/en-US/docs/Web/CSS/filter#interpolation - "missing equivalent filter functions from the longer list are added to the end of the shorter list using their initial values." In the attached demo, however, Webkit does not play the transition and directly jumps to the final state when hovering. Firefox and Chrome correctly fill in the missing filter function with its initial value.
