title: Got ckeditor-duplicated-modules when integrate ckeditor5 into Angular project
body: <p>I tried to integrate ckeditor5 into my angular project but got <code>ckeditor-duplicated-modules</code>. I tried many ways</p>
  
  <ol>
  <li><p>Add ckeditor classic build only, it works fine</p></li>
  <li><p>Add ckeditor classic build and <code>Base64ImageUpload</code> plugin, it does not work</p></li>
  <li><p>Extend my <code>ClassicEditor</code> from <code>ClassicEditorBase</code> but it does not work</p></li>
  </ol>
