The effect actually isn't as large as I previously thought.  The
effects of 'flex-align' on an anonymous block around the placeholder
end up being about the same as applying them the placeholder itself.
Possibly identical, but I'm not certain off the top of my head.  It
may be simply that the only observable effect is to make two abspos
elements next to each other still take up two "spots" for the purpose
of flex-pack:justify and such.
