[csswg-drafts] [css-text] The computed value and animation type of tab-size

upsuper has just created a new issue for 
https://github.com/w3c/csswg-drafts:

== [css-text] The computed value and animation type of tab-size ==
The current spec says the computed value of `tab-size` is "the 
specified integer or length made absolute", however the animation type
 is "length".

It seems to me animation is based on computed value, which means 
either `<integer>` value is not interpolatable, or `<integer>` should 
be converted into `<length>` when it becomes computed value.
