Re: [csswg-drafts] Definiteness of flex items' main size depend on flex-basis's definiteness

Issue here is that Grid's behavior comes from the fact that, while there may be some definite/indefinite shenanigans while figuring out how large the tracks are, once you do so, the tracks (and thus, the grid areas) have a definite size in px.  If you then stretch the grid item into that space, they're considered definite as well, so child %s resolve.

Flexbox doesn't have this two-tier notion. There's nothing in the spec currently to support the flex item's main size being treated as definite in this case; it's auto-height, and none of the special cases in [Flexbox/9.8](https://drafts.csswg.org/css-flexbox/#definite-sizes) apply.  If you or a Firefox dev can tell us how you're getting it to have a definite size, that would be great. ^_^
