@aristath Any feedback on this?

Isn't normal the same as 1? (Unitless)

[anthonyryanrusso]

No unfortunately "1" is not the same as "normal".

According to the spec, a value of "normal" is not just a single concrete value that is applied to all elements, but rather computes to a "reasonable" value depending on the font size set (or inherited) on the element.

Fixed. Problem was with the sanitization function 👍
