Do those spaces _render_?  That depends on the value of white-space, as 
you say.  The usual rules of 
http://www.w3.org/TR/CSS21/text.html#white-space-model are applied to 
the anonymous block, and would normally cause leading and trailing 
whitespace inside a block to not render if white-space is 'normal'. 
There's no need to explicitly specify this in flexbox, since it falls 
directly out of the anonymous item being a block-inside.

That's actually not what the current spec says, per earlier discussion 
on this list, and not what Gecko's implementation will do.  In 
particular, in your example above, if the <div> is white-space:pre there 
will be exactly three flexbox items: an image, a block with some text 
including non-collapsible whitespace, and a second image.
