DataGrid problem with SelectionType=Row

I have found that when the DataGrid with SelectionType="Row" is placed on a tab, and a row is selected, and then the user switches to another tab, and then back to the DataGrid tab, the row selection no longer works properly. As each new row is selected the formerly selected rows do not get de-selected. I have reproduced this problem in the Sample Explorer on the "Data Grid" page with the following modification to the XAML:

<local:DemoDisplay.DemoContent>
    <TabControl>
        <TabItem Header="DataGrid">
            <ms:DataGrid ItemsSource="{Binding Data}" ShowColumnHeaders="{Binding ShowColumnHeaders}" ShowRowHeaders="{Binding ShowRowHeaders}"
             AllowColumnReorder="{Binding AllowColumnReorder}" AllowEditing="{Binding AllowEditing}" CellEditModeBehavior="{Binding EditModeBehavior}"
                         SelectionType="Row">
                <ms:DataGrid.Columns>
                    <ms:DataGridColumn PropertyName="FavoriteColor" Width="150" />
                    <ms:DataGridColumn PropertyName="Surname" Width="120" />
                </ms:DataGrid.Columns>
            </ms:DataGrid>
        </TabItem>
        <TabItem Header="Other Tab">
            <TextBlock Text="Nothing Here" HorizontalAlignment="Center" VerticalAlignment="Center"/>
        </TabItem>
    </TabControl>

I am using the nightly build from 22-Jan-2016.

Hi Peter,

Thanks for brining this to our attention and providing the repro code. This issue will be resolved in the next nightly build.
