[csswg-drafts] [css-flexbox] Should fully inflexible item have definite height even with min-height: auto? (#4305)

== [css-flexbox] Should fully inflexible item have definite height even with min-height: auto? ==
https://drafts.csswg.org/css-flexbox/#definite-sizes says:

However, with min-height: auto, such an item may well require layout to determine its size (in a column flexbox where the item has `height: auto; flex: 0 0 100px;`). Should its size still be considered definite?
