Wouldn't this contradict the subsequent clarification: "A box's own margins
collapse if the 'min-height'
<http://dev.w3.org/csswg/css2/visudet.html#propdef-min-height> property is
zero, and it has neither top or bottom borders nor top or bottom padding,
and it has a 'height'
<http://dev.w3.org/csswg/css2/visudet.html#propdef-height> of either 0 or
'auto', and it does not contain a line box, and all of its in-flow
children's margins (if any) collapse."
