The way we could make it work would be to change the logic in the <select> 
so that when it's in a canvas, it's a list box and not a drop-down. But 
that might be more confusing than requiring that people set size=2? I 
guess I'll just punt on this for now and we'll see whether authors get 
confused or not.
