title: Looping HTML5 video with Rails and HAML video_tag
body: <p>I'm using Rails video_tag to render a video as so:</p>
  
  <pre><code>= video_tag("SMR_video.mp4", :controls =&gt; false, :autobuffer =&gt; true, :autoplay =&gt; true, :loop =&gt; true, :id =&gt; "hero-video")
  </code></pre>
  
  <p>This results in the following, the video doesn't loop:</p>
  
  <pre><code>&lt;video autobuffer="autobuffer" autoplay="autoplay" id="hero-video" loop="loop" src="/assets/SMR_video.mp4"&gt;&lt;/video&gt;
  </code></pre>
  
  <p>Where am I going wrong here?</p>
  
  <p>Thanks</p>
