[css-houdini-drafts] [css-properties-values-api] Composition behavior of lists

andruud has just created a new issue for https://github.com/w3c/css-houdini-drafts:

== [css-properties-values-api] Composition behavior of lists ==
When doing a `composite:'add'` between two custom property lists, what should happen? Are the lists concatenated, or are they added component-wise?

There doesn't seem to be a default behavior specified anywhere for _simple lists_.

See also relevant text in [web-animations-1](https://drafts.csswg.org/web-animations-1/#procedures-for-animating-properties), under **accumulate**.
