[css-typed-om-1] CSSVariableReferenceValue's "variable" getter needs to be defined.

[bzbarsky]

Presumably it returns the "variable" internal slot's value?

[darrnshn]

I'm guessing you meant CSSVariableReferenceValue?

[bzbarsky]

Er, yes, I do. They're kinda lumped together in a way that confused me. ;(

Fixed in #676.

(I left it out on the assumption that, if undefined, it just does the normal thing. Specs generally leave off both getters and setters for attributes that just reflect the internal slot.)
