title: GM_addStyle function is not working in Tampermonkey?
body: <p>I'm using Tampermonkey and trying to change the CSS of the body tag. However the usual way to add CSS doesn't work,</p>
  
  <p><code>GM_addStyle("body {overflow:visible !important}");</code></p>
  
  <p>I think because the CSS I'm trying to change is added inline by a script. Dev tools indicates <code>overflow: hidden</code> is an inline style; and the overflow: hidden style only appears in dev tools, not in "view source".</p>
  
  <p><code>&lt;body class="fixed-scroll-nav blah-blah-blah" style="overflow: hidden;"&gt;</code></p>
  
  <p>I have the Tampermonkey script set to run at <code>document-end</code>. I can manually add overflow: hidden in dev tools and confirm it's the correct selector. </p>
  
  <p>Do I need a different JavaScript or Tampermonkey function?</p>
