Created Unassigned: Enter after changing DateTimePicker in a DataGrid... [21714]

When I press ENTER after I'm finished editing a DateTimePicker which is in a DataGrid it doesn't trigger RowEditEnding. If I change the control for a standard DatePicker it works.

```
<DataGridTemplateColumn ClipboardContentBinding="{x:Null}" Header="Created Date">
<DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<xctk:DateTimePicker AutoCloseCalendar="True" Value="{Binding CreatedDate, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"/>
</DataTemplate>
</DataGridTemplateColumn.CellTemplate>
</DataGridTemplateColumn>

```
