Comment (by sergej.mueller):

 '''How to test it'''

 1. Open ''Developer Tools'' in your browser. Switch to ''Network'' tab.
 2. Reload a admin page (e.g. dashboard) and monitor the requested files in
 dev tools.
 3. Look for ''load-scripts.php'' and ''load-styles.php'' files.

 - Before patch both files provide a ''200 status code'' and give back all
 of requested CSS/JS code.
 - After patch WordPress will return a ''304 status code'' (''Not
 Modified''
 http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5) and send
 plain header without content.
