VirtualizingStackPanel中的WrapPanel在调整大小时无法正确重绘

Question

我有一个具有虚拟化功能的ItemsControl。作为DataTemplate，我有一个WrapPanel。问题是当我调整容器大小时，包装面板不能正确重新绘制。它包装新行以包装文本，但文本仍保留在顶行。

我创建了一个简单的测试项目来显示问题。 这是XAML :( MainWindow.xaml）

            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</Window>

这是代码：（MainWindow.xaml.cs）

using System.Linq;
using System.Windows;

namespace WpfApplication1
{
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();

            this.Items.ItemsSource = Enumerable.Range( 0, 30 );
        }
    }
}
