[css-sizing-3] Why was min-content, etc. redefined to do nothing in the block axis? #3973

https://drafts.csswg.org/css-sizing-3/#sizing-values

min-content
If specified for the inline axis, use the min-content inline size; otherwise behaves as the property’s initial value.

Why is it now defined this way (it didn't use to be)? This makes it impossible to use this property in min/max-block-size properties, which is useful.

(Chrome's UI was using it, until https://chromium-review.googlesource.com/c/chromium/src/+/1599691 broke it when we matched the spec)
