title: select2 select2-removed event find tag position
body: <p>I have a select2 multiple tag control (limited to 2 in my case) where the positions of the tags are important.</p>
  
  <p>I am listing on the select2-removed event, and want to find the position of the tag being removed.</p>
  
  <p>I am able to break on the remove event, and inspect e, but this give me the id of the element, not the position in the tag field.</p>
  
  <pre><code>$('#mytags').on('select2-removed', function(e){
  
       console.log('removed', e)
  
  });
  </code></pre>
  
  <p>How can I determine which tag (first or second) was removed?</p>
