 === Description
 ✅ This report validates that the patch works as expected.

 Patch tested: https://github.com/WordPress/wordpress-develop/pull/11588

 === Environment
 - WordPress: 7.1-alpha-20260416.100837

 === Steps to Test
 1. Apply the patch from the linked pull request to a WordPress
 installation.
 2. Navigate to Tools > Theme File Editor (theme-editor.php).
 3. Resize the browser window to a small viewport width (e.g., below 768px
 or mobile-sized).
 4. Observe whether a horizontal scrollbar appears on the Theme Files
 section.
 5. Navigate to Tools > Plugin File Editor (plugin-editor.php).
 6. Again, resize the browser window to a small viewport width.
 7. Observe whether a horizontal scrollbar appears on the Plugin Files
 section.

 === Actual Results
 1.  ✅ Issue resolved with patch.
 2. Unnecessary horizontal scrollbar on theme-editor.php is resolved with
 the patch — no horizontal scroll at small widths.
 3. Unnecessary horizontal scrollbar on plugin-editor.php is also resolved
