 In multisite, if a Super Admin's email is a case-insensitive match to the
 Network Admin email, the checkbox for revoking super-admin shows, but
 doesn't work.

 Reproduction:
  - set Network Admin email to `Admin at example.test`
  - set a Super Admin's email to `admin at example.test`
  - attempt to revoke super admin from same user

 This will fail because of the case-insensitive comparison here:
 https://core.trac.wordpress.org/browser/trunk/src/wp-
 includes/capabilities.php#L922

 In typical circumstances (when emails do not have a case difference) the
 checkbox doesn't show because of comparison here:
 https://core.trac.wordpress.org/browser/trunk/src/wp-admin/user-
 edit.php#L420

 Looks like this has been an issue since about 3.1, maybe older.
