Bug report

In DropDownlist with virtualization, the change event will be triggered twice when filtering and selecting an item that is not on the current page.

Reproduction of the problem

1. Go to this Dojo example.
2. Open the dropdown and type Lila in the filter input field.
3. Select the one with Id 10780. -> Change event is triggered as expected.
4. Then re-open and click outside the dropdown, so that the widget would lose focus.

Current behavior

The change event is triggered again, even though the value has not been changed.

Expected/desired behavior

The change event should NOT be triggered again, as the value has not been changed.
