[csswg-drafts] [css-sizing] {min, max}-{width, height} and intrinsic size keyword values

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

== [css-sizing] {min,max}-{width,height} and intrinsic size keyword 
values ==
In [the section for the new 
keywords](https://drafts.csswg.org/css-sizing-3/#width-height-keywords),
 the spec states:
> If specified for the inline axis, use ...; otherwise compute to 
auto.

for `{max,min,fit}-content` keywords. However, there is no definition 
for `auto` value of `{min,max}-{width,height}` at all in CSS2 ([for 
`{min,max}-width`](https://www.w3.org/TR/CSS22/visudet.html#min-max-widths),
 [for 
`{min,max}-height`](https://www.w3.org/TR/CSS22/visudet.html#min-max-heights)).

It is probably better making it compute to the initial value of the 
corresponding property?
