title: HTML markup validator -alert duplicate attributes- in VS Code
body: <p>Is there a plugin or factory settings to alert duplicates in HTML attributes in the Code editor VisualStudio?.</p>
  
  <p>To check:</p>
  
  <ul>
  <li>Initial spaces, </li>
  <li>Attributes duplicates.</li>
  </ul>
  
  <p>As a refactor...</p>
  
  <p>Something similar as VisualStudio-Community, which does.
  <strong>I.e:</strong>

  <p>Thanks.</p>
