title: Uncaught TypeError: Cannot redefine property: ytplayer
body: <p>I'm trying to make a site that includes embedded Youtube videos.
  From out of the blue, seemingly, the console in Chrome inspector began showing the following error:</p>
  
  <blockquote>
    <p>Uncaught TypeError: Cannot redefine property: ytplayer</p>
  </blockquote>
  
  <p>It does not seem to really affect anything.</p>
  
  <p>I then created a completely blank document, embedded a fresh video onto it and recieved the same error.
  It even appears on Youtube itself, for me.
  Does anyone have any idea on what this is?</p>
