That is not true. Or at least not completely true: IE 6 & 7 ignore  
that definition (only) when 'haslayout' is triggered on the static,  
non-floated block (e.g. using width). And in that case the non-floated  
block is displaced, not wrapped around the float.
That IE behaviour is somewhat similar to what CSS 2.1 compliant  
browsers do when the non-floated block establishes a new block- 
formatting context (per 9.4.1).
