Comment (by cypherpunks):

 Do nested schemes (`view-source:`, `jar:`, etc.) leak information about
 existing restricted resources? Although I tend to think those schemes are
 inaccessible from content, that does not necessarily guarantee no
 information leak.

 Ex.
 Is `view-source:chrome://nonexistent/content/` denied the same way as
 `view-source:chrome://torbutton/content/`?
