title: dropzone.js is giving error "Invalid dropzone element" on page without a dropzone
body: <p>I'm using dropzone js and it's working great on pages that I require a dropzone. On any other page though it's giving me a <code>"Invalid dropzone element"</code> error message and causing issues with my other javascript.</p>
  
  <p>I have a custom JS file (which loads immediately after the dropzone.js file) and at the very top of the file I have the following line of code:</p>
  
  <pre><code>Dropzone.autoDiscover = false;
  </code></pre>
  
  <p>This should stop it from looking at any page where I'm not enabling it programatically. The error only goes away on pages where there is a valid dropzone.</p>
  
  <p>I also set the following code on line 1470 on dropzone.js to try and enable it there too:</p>
  
  <pre><code>Dropzone.autoDiscover = false;
  </code></pre>
  
  <p>How can I get rid of this error?</p>
