When binding another control to a shared SelectedItem property from a ViewModel causes the Item to not be updated correctly to the ListBox and the anther control.

Available in LIB version 2015.3.1019, it will be also available in the 2015 Q3 SP1. Fix provided by the new IsScrollIntoViewEnabled property.

Using an attached property to populate the SelectedItems of the control initially selects only the first item.
