ListBox display error

[Linlccc]

Describe the bug

After quickly scrolling up and down in the ListBox, some extra display items appear mysteriously, as shown in the figure, such as 80 and 86.

To Reproduce

ViewModel

public class TestViewModel : ViewModelBase
{
    public class MyClass(string text, bool isImage)
    {
        public string Text { get; set; } = text;

        // Load random exception image
        public Bitmap? Image { get; set; } = isImage ? new Bitmap("/Users/lin/Pictures/截屏与录制/2484ed39-3cf6-4393-8dc4-fddfcee410b3.png") : null;
    }

    public ObservableCollection<MyClass> List { get; set; }
    public MyClass SelectedItem { get; set; }

    public TestViewModel()
    {
        List = [];
        for (int i = 0; i < 300; i++)
        {
            List.Add(new MyClass($"测试{i}", i % 3 == 0));
        }
        SelectedItem = List[0];
    }
}

Backend code

private void ClipItem_OnPointerEntered(object? sender, PointerEventArgs e)
{
    if (sender is Control { Parent: ListBoxItem listBoxItem }) listBoxItem.IsSelected = true;
}

View

<ListBox Grid.Row="1" IsVisible="True" ItemsSource="{Binding List}" SelectedItem="{Binding SelectedItem}">
    <ListBox.ItemTemplate>
        <DataTemplate>
            <Border Background="Transparent" PointerEntered="ClipItem_OnPointerEntered">
                <Grid ColumnDefinitions="*,Auto" Margin="9,3">
                    <StackPanel>
                        <TextBlock Text="{Binding Text}" FontSize="12" />
                        <Image Source="{Binding Image}" />
                    </StackPanel>
                    <ContentControl Grid.Column="1" x:Name="itemRight" />
                </Grid>
            </Border>
        </DataTemplate>
    </ListBox.ItemTemplate>
</ListBox>

Does it reproduce without selection on pointer over?
You can try to change this line:

-    if (sender is Control { Parent: ListBoxItem listBoxItem }) listBoxItem.IsSelected = true;
+    if (sender is Control { Parent: ListBoxItem listBoxItem }) listBoxItem.SetCurrentValue(ListBoxItem.IsSelectedProperty, true);

Does it reproduce without selection on pointer over? You can try to change this line:

• if (sender is Control { Parent: ListBoxItem listBoxItem }) listBoxItem.IsSelected = true;

• if (sender is Control { Parent: ListBoxItem listBoxItem }) listBoxItem.SetCurrentValue(ListBoxItem.IsSelectedProperty, true);

The error display still occurs after the modification.
