title: Is it possible to inspect `GM_xmlhttpRequest`s in the Developer Tools network tab?
body: <p>I found out that you can perform a CORS request within a Tampermonkey script using <code>GM_xmlhttpRequest()</code>.  Unfortunately, they don't appear in the Chrome devtools network tab.</p>
  
  <p>I know GM_ functions are running in their own scope somewhere within the extension.  </p>
  
  <p>Is there a way to inspect such requests?</p>
