[css-align] "whichever matches its inline axis" is ambiguous

[dbaron]

The section on Baseline Content-Alignment says:

A grid item participates in first (last) baseline content-alignment in its startmost (endmost) row or column (whichever matches its inline axis) if...

The "(whichever matches its inline axis)" here is ambiguous. It's not clear what "matches" means.

I think the parenthetical should instead say "(whichever axis is parallel to its inline axis)".

Though, really, they could be either parallel or anti-parallel, they just can't be perpendicular!

I filed issue #425 under the same rationale for Baseline Self-Alignment. As a matter of fact, such text was removed from the Baseline Self-Alignment prose in commit #2698f3c

Fixed in 5a9bbe9, thanks! (We don't think anti-parallel is a relevant consideration here, they're not directional and in general English anti-parallel is a subset of parallel anyway.)
