 == Test Report

 === Description
 This report validates whether the proposed patch resolves the issue
 described this ticket.

 Patch tested: https://github.com/WordPress/wordpress-develop/pull/9042

 === Environment
 - WordPress: 6.9-alpha-60093-src
 - PHP: 8.2.28
 - Server: nginx/1.27.5
 - Database: mysqli (Server: 8.4.5 / Client: mysqlnd 8.2.28)
 - Browser: Chrome 137.0.0.0
 - OS: Linux
 - Theme: Twenty Fifteen 4.0
 - MU Plugins: None activated
 - Plugins:
   • Classic Widgets 0.3
   • Test Reports 1.2.0

 === Actual Results
 Tested using the same reproduction steps outlined in comment:15.

 📝 For others testing this patch, please refer to those steps. In my case,
 I did not need to repeat them since my local environment was already
 configured.

 ✅ The patch resolves the issue.

 Escaped HTML entities such as `<em>` in RSS feed titles are now properly
 decoded and stripped before display, resulting in clean, readable titles.

 === ℹ️ Additional Notes
 - ⚠️ Ensure you are using an older bundled theme (e.g., **Twenty
 Fifteen**) that supports classic sidebars.
 - ⚠️ Activate the **Classic Widgets** plugin —
 https://wordpress.org/plugins/classic-widgets/
 - ⚠️ This plugin disables the block-based widget editor to expose the
 legacy **RSS Widget**, which is necessary for testing this behavior.

 widgets/tags/0.3/classic-widgets.php
