All of the top four browser vendors would like to have these kinds of  
details clearly specified and to converge on interoperable behavior. I  
am not aware of any vendor that specifically wishes to diverge from  
interoperable behavior. As such, I hope the editor politely declines  
your requests to leave such things unspecified.

In general, leaving things unspecified does not prevent Web content  
from relying on them, it just hurts cross-browser interoperability and  
makes the lives of Web developers and browsers alike more painful. You  
have not presented any argument that outweighs such considerations.

Maciej
