stephenmcgruer has just created a new issue for https://github.com/w3c/csswg-drafts: == [css-backgrounds-3] Clarification on animation additive composite behavior for box-shadow == Currently the spec for box-shadow (https://drafts.csswg.org/css-backgrounds/#box-shadow) does not appear (to my quick reading) to give any instructions for additive composition (https://drafts.csswg.org/web-animations-1/#effect-composition) when animating. In the absence of a behavior for addition, the fallback is to use replace (https://drafts.csswg.org/css-values-4/#combining-values). Firefox instead appears to implement box-shadow interpolation as list concatenation, as shown by https://output.jsbin.com/pikiguv. Chrome appears to do component-wise addition. Which, if either, is correct? Please view or discuss this issue at https://github.com/w3c/csswg-drafts/issues/4330 using your GitHub account
