wp_update_user() is the 'user_email' now a required $userdata arg for updating a user ?

in r32820 there's a new check on $userdata['user_email'] to see if an email should be send if i understand well.

My problem is: if i want to update the display name, doing something like this :

// Update the display_name
wp_update_user( array(
	'ID'                  => $user_id,
	'display_name' => $display_name,
) );

Then i get an error because $userdata['user_email'] is not set in my array.

If the user_email is now required, then simply close this ticket.

imho maybe an isset( $userdata['user_mail'] ) before comparing it to $useruser_email would be nice, because i might not be the only one using wp_update_user() the way i've described above.

Confirmed. This change is also breaking a lot of unit tests.

In 32838:

When updating a user, only send email-change notification if email address is passed.

The notification, introduced in [32380], was firing incorrectly (and throwing
a PHP notice) when wp_update_user() was called without including 'user_email'
in the update data.

Props imath.
Fixes #32684. See #32430.
