Stop ComboBox from scrolling to top

In WPF, is there any way to disable the scroll behavior of the ComboBox that auto-scrolls to the top of the list whenever a user reaches the end of the list? I'd rather that the list stayed at the end and the user have to manually scroll back to the top.

Heres the XAML for the ComboBox:

 <ComboBox x:Name="CellProviderCombo" HorizontalAlignment="Left" Height="65" Margin="14,405,0,0" VerticalAlignment="Top" Width=" 327" Header="Cell Provider" PlaceholderText="Choose Cell Provider" DataContext="{StaticResource GlobalVars}" ItemsSource="{Binding GlobalShopInfo.CellProviders}" DisplayMemberPath="Name" SelectedValuePath="Name" IsDoubleTapEnabled="False"/>

As I said, if you scroll past the last element in the combobox it simply starts over at the bottom and the scroll bar shoots back up to the top automatically.

Turns out that the ComboBox in WPF is not the same ComboBox used in Windows Apps Windows.UI.Xaml.

The ComboBox used in Windows Apps uses a Carousel instead of a StackPanel to display its items. One of the effects this has is making it so when you reach the end of the list, it simply loops back to the top. The solution is to manually change the ItemsPanelTemplate to a StackPanel as follows:

<ComboBox x:Name="MyComboBox"> //Add other properties in this line as well if needed
    <ComboBox.ItemsPanel>
        <ItemsPanelTemplate>
            <StackPanel Orientation="Vertical"/>
        </ItemsPanelTemplate>
    </ComboBox.ItemsPanel>
</ComboBox>

Hope this helps anyone who has a similar issue.
