title: What happens to files uploading in a browser when the app is changed?
body: <p>When uploading a file in Chrome on Android, what happens when a call comes in, or the app is moved to the background? From what I can tell, it seems that the file upload is interrupted.</p>
  <p>I am working on a mobile website that is a few years old, and there is a jQuery file upload plugin that allows multiple files to be uploaded, and the uploads all fail when a call comes in...</p>
  <p>I am in the beginning stages of investigating this, and don't quite understand how the browser handles uploads when calls come in, or apps are switched, so not sure where to start addressing the usability issue.</p>
  <p>Thanks!</p>
