title: VS code doesn't gray out unused variables
body: <p>As far as I know it seems this is the setting you enter in your <code>settings.json</code> to enable unused variables &amp; imports that aren't used to appear grayed out.</p>
  
  <pre><code>"editor.showUnused": true,
  </code></pre>
  
  <p>I do get an underline and if you hover I get an underline and message on hover.</p>
  
  <p>What am I missing?</p>
