 Test 6/n

 **Environment:** WordPress on the tip, after August 20 or so and with
 https://github.com/WordPress/wordpress-develop/pull/5237 applied. You need
 no plugins. You may use Mailpit 1.25.0 or later to pick up outgoing mail.
 Mailpit needs to listen on localhost port 25.

 I used Brave as browser and ran both on linux.

 **Steps to test:** Open the WordPress admin page. Select "users" on the
 left-hand bar, then "add new user" near the top of the screen. Enter "grå"
 as username, "grå@grå.org" as email address. Choose any name and role.
 Click "add new user" near the bottom. (Grå is Norwegian, it means grey,
 and I use that as a test since I'm Norwegian. It's pronounced as org
 backwards.)

 Open an incognito/guest browser window, open wp-admin and log in as grå
 with the correct password. Click Profile, then edit the email address to
 blå@grå.org and click 'Update Profile'.

 **Test results:** All is well if WordPress sends email to blå@grå.org with
 a link to confirm the email address, and clicking the link leads to the
 expected page works, and the new addres can then be used to log in.
 WordPress 6.8 will not send the mail.
