<p dir="auto"><strong>Current behavior</strong><br>
I have two tags select bound to the same list, after changing the selection a couple times I can see items from the first select being overridden by the second select selection.<br>
This happens when I was testing bindings types on <em>select</em> with <em>ngValue</em>, <em>value</em> and a <em>change</em> event.</p>
<p dir="auto"><strong>Expected behavior</strong><br>
The list instance should not change.</p>
<p dir="auto"><strong>Minimal reproduction of the problem with instructions</strong><br>
This behavior seems ramdom, you'll need to change selection in both drop down a couple times before both select start containing only one duplicated object.<br>
Here is a plunker on version 2.4.7: <a href="http://plnkr.co/edit/u4Owq7NeP5GMlUGrR9Oa?p=preview" rel="nofollow">http://plnkr.co/edit/u4Owq7NeP5GMlUGrR9Oa?p=preview</a></p>
