[css3-flexbox] Flexbox baseline when overflow is non-visible

http://dev.w3.org/csswg/css3-flexbox/#flex-baselines

I cannot find any mention of what to do for flexboxes with non-visible
overflow in the flexbox spec. CSS 2.1, on the other hand, says that if
an inline-block has non-visible overflow, its baseline is its bottom
margin edge. Wouldn't it make sense to do the same for inline-flex? What
if the relevant item's baseline is in the overflowed area of its flex
container?
