Well, you could still phrase it something along the lines of "The size 
of a popup document's viewport SHOULD be calculated using the CSS shrink 
wrap algorithm... etc etc".

All I really just want is to make sure browsers don't use today's 
implentations. If you open a popup/modal dialog today and don't specify 
a size, you usually end up with an arbitrary default size or even a 
full-fledged second browser window the size of your screen - both pretty 
ill-fitted for the use-cases of showModalDialog() IMO.

Example:
data:text/html,<button 
onclick="window.showModalDialog('data:text/html,<div style=\'width:1000; 
height:100; border: 1px solid black;\'>Awkward-sized dialog 
box</div>');">Click me!</button>
