title: Request Picture In Picture on scroll chrome
body: <p>I want to use chrome's PIP when video is out of viewport by using scroll event listener. Chrome gives this error: </p>
  
  <blockquote>
    <p>Must be handling a user gesture to request picture in picture.</p>
  </blockquote>
  
  <p>Can someone confirm if scroll is a user gesture or not? If it is why this error?</p>
