title: HTTP request delayed in Chrome if dev tools not open
body: <p>I'm working on a <a href="http://34.213.8.35/tree" rel="nofollow noreferrer">webpage</a> in an app that uses some JavaScript to fetch data from an <a href="http://34.213.8.35/api/tree" rel="nofollow noreferrer">API endpoint</a>.</p>
  
  <p>In Safari and FireFox, I can request the page multiple times in a row and the data is fetched and displayed promptly. In Chrome, by contrast, the data is fetched and displayed promptly only if the dev tools are open or if my cache is clear (though I'm not disabling the cache in the dev tools).</p>
  
  <p>If the dev tools are not open or Chrome has cached the page, reloading the page takes about 10 seconds to make the request and display the data.</p>
  
  <p>Does anyone have any idea what might be causing this behavior? <a href="https://s3-us-west-2.amazonaws.com/lab-apps/let-them-speak/let-them-speak.tar.gz" rel="nofollow noreferrer">Full app source</a>.</p>
