title: Duplicate List Items in Angular: Unable to select first item
body: <p>I have a list (select) box which is dynamically populated with numbers. Some of these numbers may be duplicates of previous entries. When I attempt to select a duplicate number which has an index lower than the other duplicate value, the list jumps to the higher indexed entry (lower down the list). I have created an example here - <a href="http://plnkr.co/edit/D8cVIauJQGOfZx9HdGsD?p=preview" rel="nofollow">http://plnkr.co/edit/D8cVIauJQGOfZx9HdGsD?p=preview</a> . Selecting the first value of 90 will show the above mentioned behavior. Selecting other, non-duplicate, entries works as expected.</p>
  
  <p>Thanks, in advance!</p>
