Ah, you're right that the shrinking only happens with a definite cross
size. Since that can be used as a constraint in the regions processing
model, that means you'll never get an answer for an auto-height region
flex item that is taller than the cross size. I'd figured that out a few
days ago, then forgot it today.

So the shrinkiness of stretch isn't a problem for regions. I still think
it's weird, though.
