title: Prevent iframe to reload
body: <p>I have a WYSIWYG editor (Tinymce).</p>
  
  <p>I use Vue.js 1 to show a preview of the editor contents real-time. If a user types in the editor, the preview updates real-time as expected. But here is a problem.</p>
  
  <p>If there is an iframe tag (Youtube video) in the preview, the video content tries to send a request to Youtube to reload as a user starts typing because the preview updates real-time. If there is only 1 video(iframe) it's ok but if there're 2 or 3 videos it gets really heavy and slow since multiple videos try to reload by themselves.</p>
  
  <p>So, is there any way to make them stop sending a request to Youtube to reload when the editor contents update real-time?</p>
