title: Safari: "Failed to load resource: cancelled" in console. What does this mean?
body: <p>I am getting this error in the safari developer console:</p>
  
  <blockquote>
    <p>Failed to load resource: cancelled</p>
  </blockquote>
  
  <p>What does this mean? I don't see any errors on the page, so why am I getting this message? I have an iframe on the page that is hidden when it loads, but it loads fine when I display it so I don't know why I'm getting this message.</p>
