Comment (by afragen):

 You can test the PR with the following plugin code. Obviously this would
 need to be added by the theme dev.


 {{{
 <?php
 /**
  * Plugin Name: Test #34986
  * Description: Testing Trac Ticket #34986
  * Author: WP Core Contributors
  * Version: 0.1
  */

 add_filter( 'site_transient_update_themes', 'add_upgrade_notice_34986',
 20, 1 );

 function add_upgrade_notice_34986($transient){
     $theme_slug = 'twentytwentythree';
     if ( isset($transient->response[$theme_slug])){
         $transient->response[$theme_slug]['upgrade_notice'] = 'Test of
 upgrade notice, #34986.';
     }

     return $transient;
 }
 }}}

 To test, decrease the local version number of the Twenty Twenty Three
 theme so that it shows an update.
