Re: [csswg-drafts] [css-backgrounds-3] Clarification on animation additive composite behavior for box-shadow (#4330)

From a developer ergonomics point of view, I think concatenation makes more sense. It's as if you are adding another shadow. As for what is correct - it is animatable as a shadow list. The definition for how to animate a shadow list moved to web-animations-1 from css-transitions-1 https://www.w3.org/TR/web-animations-1/#animating-shadow-lists which suggests it should be component-wise.
