Yeah, indeed, thanks.

A separate case I was thinking about is more than one <img>s in a  
<picture>, do we want both to work or just the first? The proposal right  
now would do both. If we want only the first, that means the selection  
algorithm needs to check that there are no previous img siblings. When an  
img is inserted to a picture so it becomes the first img, we need to rerun  
the selection algorithm on the next img sibling (i.e. the img element that  
was previously the first). Similarly when an img element is removed, the  
(new) first img child needs to run the selection algorithm. Although it  
involves more checks, I think it seems saner to have only the first img  
use the <source>s.
