Comment:

 27606.patch fixes the issue.

 The case of Network Admin > Add New User was straightforward. The case of
 Multisite > Add New User was a bit different, because a `wp_redirect()`
 takes place after the error, which means we lose the values submitted in
 `$_POST`. I've opted to add them as URL parameters when redirecting.

 > when autocomplete is in use, we really should only allow selection of an
 option and not the submission of freeform typing

 Yes, but that's a bigger fish to fry, so I wrote a fix for the current
 implementation.
