Probably don't need "Helper" in the name.

Done.

[alancutter (OOO until 2018), 2016/01/21 00:58:38]

count() doesn't make sense outside of UseCounter, perhaps suppress().

[nainar, 2016/01/21 02:39:07]

Done.

[alancutter (OOO until 2018), 2016/01/21 00:58:38]

Why is CSSPropertyInvalid a valid propertyID?

[nainar, 2016/01/21 02:39:07]

Fixed.
