title: Datepicker changes to default when entering 'mm/dd/yy'
body: <p>When a user manually enters or copy/pastes a date that is formatted 'dd/mm/yy' the date picker changes the date entered into the default date.  The format is 'dd/mm/yyyy.'  So when you manually or copy and paste using that format it works.  Is there a utility in moment or a datepicker property that can recognize both dd/mm/yy as well as the dd/mm/yyyy.</p>
