I believe this might require a multi-step layout if more complex
situations are to be handled. Consider the following case:
<flexbox>
	<region_1 height=auto></region_1>
</flexbox>
<flexbox>
	<region_2 height=auto></region_2>
</flexbox>

The layout for the second flexbox would require the height for region_2
to be computed which can only be known _after_ the content has been flowed
in region_1 and the first flexbox has flexed its size.
