Comment:

 == Test Report
 === Description
 This report confirms that the proposed patch functions as intended, adding
 new filters for several Multisite-related email subjects.


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

 === Environment
 - WordPress: 6.9-alpha-60093-src
 - PHP: 8.2.29
 - Server: nginx/1.29.1
 - Database: mysqli (Server: 8.4.6 / Client: mysqlnd 8.2.29)
 - Browser: Chrome 140.0.0.0
 - OS: Windows 10/11
 - Theme: Twenty Twenty-Five 1.3
 - MU Plugins:
   * test.php
 - Plugins:
   * Email Log 2.6
   * Test Reports 1.2.0

 === Actual Results
 Without the patch:
 The filters are not available.

 With the patch applied:

 ✅ delete_site_email_subject — works as expected when deleting a site from
 the network.

 ✅ newblog_notify_siteadmin_subject — works as expected when a user
 creates a new site.

 ✅ newuser_notify_siteadmin_subject — works as expected when a new user
 registers on the network.

 ✅ new_user_email_subject — works as expected when a user updates their
 email address from their profile.

 === Additional Notes
 The following code was used to test the filters:
 {{{#!php
 <?php
 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';
 } );

 }}}
