[css-values-4] Simplification algorithm should account for products of min / max.

Step 8 wouldn't simplify something like a * min(b, c) into min(a * b, a * c) (or the equivalent max if a is negative), and it probably should.

Hm, you really want to distribute multiplication over min/max? If we're being consistent, it should distribute over rem() as well, maybe round()?

I think I'd prefer keeping it not distributing over anything besides addition.

That is an ok answer for me for me I guess. I think

In a world where the only other functions are min / max / clamp, you can redistribute product and then forget about multiplication pretty much right after parsing.

But I guess since we added a bunch of new functions where the product doesn't distribute so easily, or at all, then probably not worth it.

Sounds good. 👍
