title: Is it possible to embed codepen into ckeditor5 like media embed?
body: <p>programmers!</p>
  <p>I am using ckeditor5 with strapi. But I could not figure out how to embed codepens. When I put recommended embed code by codepen itself, it just shows : <code>See pen &lt;a href=&quot;...&quot;/&gt;</code>. If i inject the code with <code>iframe</code> it is just disappearing.</p>
  <p>Anyone has ever done it ?</p>
