clamp() throwing an incorrect error

[JoshBeveridge]

It seems that using clamp() as a value in both height and font-size both fail validation. This is likely a problem with clamp() across all properties.

Specifically, I'm using the basic examples from MDN as a test case:

height: clamp(1rem, 10vw, 2rem);

font-size: clamp(1rem, 10vw, 2rem);

this is similar to #27

seems a bug in https://github.com/mdn/data/, I'll check it

same cases existed in other css math functions: https://drafts.csswg.org/css-values/#math
