title: Use a Loader with too fast request
body: <p>A quick question, how do you handle requests that are too fast to show correctly a loader ?</p>
  
  <p>I have a submit button which show a loader until firebase respond (ajax request). But firebase is too fast (&lt; 10ms) so my loader is showing very fast and it's not very nice.</p>
  
  <p>Do you have any advices for it ? I would like to avoid setTimeout as possible...</p>
  
  <p>Thanks</p>
