Comment (by thomaswm):

 Just realized that `grant_super_admin()` and `revoke_super_admin()` are
 also affected.

 Lines [https://core.trac.wordpress.org/browser/tags/4.9/src/wp-
 includes/capabilities.php#L820 820] and
 [https://core.trac.wordpress.org/browser/tags/4.9/src/wp-
 includes/capabilities.php#L867 867] in `wp-includes/capabilities.php` both
 read:

 {{{#!php
 $super_admins = get_site_option( 'site_admins', array( 'admin' ) );
 }}}
