Description

Steps to reproduce:
1. Create a DrownDownList, binding a selectedItem and an arrayCollection to the dataprovider
2. Change the selectedItem (it is not in the dataprovider at this point)
3. Change the dataprovider, selectedItem is now in the dataprovider, but selected index is now -1

Actual Results:
Nothing is selected

Expected Results:
SelectedItem is in DataProvider, it should be selected.

Workaround (if any):
Instead of binding against selectedItem, can bind selectedIndex with selectedIndex="

{dataProvider.indexOf(selectedItem)}
