[csswg-drafts] [css-color-5] How should checking for percentages summing to 0 work in color-mix() when calc() is used? (#11714)

weinig has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-color-5] How should checking for percentages summing to 0 work in color-mix() when calc() is used? ==
I filed a related issue for `dynamic-range-limit-mix()`, https://github.com/w3c/csswg-drafts/issues/11678, but the same issue exists for `color-mix()`.

In the "percent normalization" algorithm, https://drafts.csswg.org/css-color-5/#color-mix-percent-norm, step 5 states:

```
5. If the percentages sum to zero, the function is invalid.
```

What should happen in the case that the percentages are `calc()` values? That is, what does it mean for the function to be invalid at style building / computed-value time?
