The map control is rendering incorrectly

Question

Microsoft Silverlight

Lord, I ask for your help, I don’t know what to do anymore.
There was a need to display the map control directly in the elements of the ListBox lists. Everything works cool, right, except for one huge jamb: when scrolling through a list that has elements with a map, the control for some reason is displayed on top of the parent container, i.e. not only the ListBox itself, but even the LayoutRoot

            <RowDefinition Height="Auto"/>
            <RowDefinition Height="*"/>
        </Grid.RowDefinitions>

        <StackPanel x:Name="TitlePanel" Grid.Row="0" Margin="12,17,0,28">
            <TextBlock x:Name="ApplicationTitle" Text="MY APPLICATION" Style="{StaticResource PhoneTextNormalStyle}"/>
            <TextBlock x:Name="PageTitle" Text="page name" Margin="9,-7,0,0" Style="{StaticResource PhoneTextTitle1Style}"/>
        </StackPanel>

        <Grid x:Name="ContentPanel" Grid.Row="1" Margin="12,0,12,0">
            <ListBox x:Name="listbox">
                <ListBox.ItemTemplate>
                    <DataTemplate>
                        <my:Map  Margin="10" />
                    </DataTemplate>
                </ListBox.ItemTemplate>
            </ListBox>
        </Grid>
    </Grid>
 
</phone:PhoneApplicationPage>

added three elements for the test:

private void LayoutRoot_Loaded(object sender, RoutedEventArgs e)
{
            listbox.Items.Add("");
            listbox.Items.Add("");
            listbox.Items.Add("");
}

Can you suggest how to get rid of this jamb? I couldn't find on google if anyone had this problem.

I asked myself, I will answer.
Instead of using the slow Bing control in lists, you should use the Image control and give it a static map image, which can be obtained by reading this documentation
