--- Comment #2 from Sam Sneddon [:gsnedders] <gsnedders at apple.com> ---
> "if the flex container has at least one flex item, the flex container’s first/last main-axis baseline set is generated from the alignment baseline of the first/last flex item. (If that item has no alignment baseline parallel to the flex container’s main axis, then one is first synthesized from its border edges.)"

We seem to do this now.

> Also, while I couldn't find it in the specs, the CSS WG has agreed that an empty Flexbox containers should synthesize its baseline using its border-box bottom edge:

It appears WebKit, Blink, and Gecko all use the margin-box for empty flexbox containers currently; not totally sure what css-flexbox and css-align say now?

So is this now resolved?
