 == Test Report
 === Description


 This report validates that the indicated patch works as expected,
 introducing new filters for various Multisite-related email subjects.

 Patch tested: https://github.com/WordPress/wordpress-develop/pull/9380

 === Environment
 - WordPress: 6.9-alpha-60093-src
 - PHP: 8.2.25
 - Server: nginx/1.27.2
 - Database: mysqli (Server: 8.4.4 / Client: mysqlnd 8.2.25)
 - Browser: Chrome 139.0.0.0
 - OS: macOS
 - Theme: Twenty Twenty-Five 1.3
 - MU Plugins: None activated
 - Plugins:
   * Test Reports 1.2.0
   * WP Mail Logging 1.14.0

 === Actual Results

 Without the patch: The filters do not exist.

 With the patch applied:

 ✅ The new filter `delete_site_email_subject` works as expected when
 deleting a site from the network.

 ✅ The new filter `newblog_notify_siteadmin_subject` works as expected
 when a new site is created by a user.

 ✅ The new filter `newuser_notify_siteadmin_subject` works as expected
 when a new user registers on the network.

 ✅ The new filter `new_user_email_subject` works as expected when a user
 changes their email address from their profile.




 === Additional Notes

 The following code was used to test the filters:


 {{{
 add_filter( 'delete_site_email_subject', function( $subject ) {
     return 'Hello World! - delete site';
 } );

 add_filter( 'newblog_notify_siteadmin_subject', function( $subject,
 $blog_id ) {
     return "Hello World! - new site";
 }, 10, 2 );

 add_filter( 'newuser_notify_siteadmin_subject', function( $subject, $user
 ) {
     return "Hello World! - new user";
 }, 10, 2 );

 add_filter( 'new_user_email_subject', function( $subject ) {
     return 'Hello World! - email change';
 } );
 }}}
