What Gecko implements right now is:
1) @download is ignored for non-same-origin links.
2) If Content-Disposition specifies a filename, that filename is used

The mimesniff standard doesn't try to sniff for types UAs don't render
natively, which is what would be needed here.

Yes, it does. "reasonable" means it's reasonable, not that it overrides
all other considerations...
