The ::backdrop specifically would just be immediately below its element in 
the "top layer" stack, at least as proposed. Could you elaborate on what 
your use case is for moving it to other layers? (Ideally with examples of 
dialogs that do this in the wild -- see the wiki page on which we designed 
the <dialog> feature -- http://wiki.whatwg.org/wiki/Dialogs -- for the 
examples that have primarily driven the design so far.)

No, that would be inherent in the <dialog> "showModal()" behaviour.

Those sound like non-modal dialogs. Do you have any examples of modal 
dialogs on the Web that have these behaviours? As above, screenshots and 
URLs to such examples would be really helpful.
