title: Input type file causes long loading
body: <p>On my webpage user can upload some file.<br>
  What is really annoying when file dialog opens, the cursor signals me, shown as circle not an arrow and being very "turbulent" , that something is loading.<br>
  The same is when I close the file dialog again.</p>
  
  <p>This is my code.</p>
  
  <pre><code>input type='file' id="btnFile" name="file" 
  </code></pre>
