Disqus module not working with BigPipe

Problem

When BigPipe (8.1.x rc1) is enabled, and the user is logged in. Disqus comments will not load.

However even when Disqus does not load, the following HTML exists.

<div data-quickedit-field-id="node/24/field_disqus/und/full">
<div id="disqus_thread">
<noscript>
  <p>
    <a href="http://localhost:8080/node/24">View the discussion thread.</a>
  </p>
</noscript>
</div>
</div>

Note that the Disqus field is not delivered using the BigPipe mechanism even if BigPipe is active.

Now when BigPipe is enabled, the ajax call in disqus.js that loads embed.js from disqus.com is not executed. (Line 69 in disqus.js)

        // Make the AJAX call to get the Disqus comments.
        jQuery.ajax({
          type: 'GET',
          url: '//' + disqus_shortname + '.disqus.com/embed.js',
          dataType: 'script',
          cache: false
        });

If I manually run this code in the console after the page is loaded, it will then load embed.js from disqus.com and the comment will load normally.
