Comment:

 This patch removes **legacy Internet Explorer (IE) specific code** and
 cleans up outdated scripts in WordPress, ensuring compatibility with
 modern browsers.

 **Changes Made:**
 - Removed IE-specific hacks in JavaScript and CSS files (e.g.,
 **imgareaselect, farbtastic, thickbox, tinymce, heartbeat.js, emoji.js,
 dashboard.js**).

 - Cleaned up IE-specific polyfills and workarounds in theme files
 (**twenty-nineteen, twenty-twenty-one**).

 - Refactored code in **functions.php and polyfills.js** to remove
 unnecessary IE support.
