Re: [csswg-drafts] [css-flexbox][css-align] Need clarification on `auto` margins for abspos flex children (do they collapse or expand)

Here's a version of my testcase with a block instead of a flexbox for 
the container:

Based on this testcase, it looks like browsers interoperably collapse 
"auto" margins on abspos children of CSS blocks. So, I suspect 
Chrome/Edge's analogous flexbox behavior is sensible (in that it's 
consistent with the traditional special-zeroing of auto margins on 
abspos elements in other contexts).

So, I think the alignment spec just needs a bit of clarification to 
make this more explicit, since IMO it's not at all clear (from the 
spec) that this behavior is correct right now.
