 == Test Report

 === Description
 This report validates whether the indicated patch works as expected.

 Patch tested: https://patch-diff.githubusercontent.com/raw/WordPress
 /wordpress-develop/pull/8836.diff

 === Environment
 - WordPress: 6.8.1
 - PHP: 8.2.23
 - Server: nginx/1.26.1
 - Database: mysqli (Server: 8.0.35 / Client: mysqlnd 8.2.23)
 - Browser: Chrome 137.0.0.0
 - OS: Windows 10/11
 - Theme: Twenty Twenty-Five 1.2
 - MU Plugins: None activated
 - Plugins:
   * Imagick Resize Filter Demo 1.0.0
   * Test Reports 1.2.0

 === Actual Results
 1.  ✅ The patch applies cleanly.
 2.  ✅ thumbnail_image() is now public and accessible externally.
 3.  ✅ imagick_resize_filter hook is available and functions correctly.
 4.  ✅ Plugin successfully overrides the default Imagick filter using the
 new hook.
 5.  ✅ Custom filter results in crisper, more optimized thumbnails without
 manually toggling filters globally.
 6.  ✅ No issues with media uploads, image cropping, or other editor
 functionality.

 === Additional Notes

 Patch test with the plugin: https://raw.githubusercontent.com/SirLouen
 /imagick-resize-filter-demo/refs/tags/1.0.0/imagick-resize-filter-demo.php

 The patch introduces two key improvements:

 1. Makes the thumbnail_image() method public, allowing plugin developers
 to directly invoke the core Imagick-based resize routine.
 2. Adds a new filter hook imagick_resize_filter, enabling developers to
 dynamically customize the Imagick filter used for resizing operations.
