Description
Describe the bug
背景，仿微信好友列表，需要在列表项头像嵌套个Badge用于标记未读消息数
<hc:Badge Value="{Binding Path=BadgeCount, RelativeSource={RelativeSource Mode=FindAncestor,AncestorType={x:Type local:ChatSessionItem}}}" Status="Text" Style="{StaticResource BadgeDanger}">
</hc:Badge>
当列表数导致项目绘制范围超出Listbox或ListView可视范围会爆出ControlTemplate无法找到Border
目前我的解决办法是吧Badge相关源码复制到项目中将BadgeBaseStyle中17-26行代码删除，就不再出现以上错误
Steps to reproduce the bug
1、创建个WPF项目
2、创建个UserControl，将Badge嵌套在Image上
3、WPF窗口创建个ListBox或ListView控件
4、引用UserControl并填至Listboxitem或Listviewitem中
5、使Listbox或listview列表内容溢出可视区域
6、bug重现

Research direction
Start with the Badge control and its BadgeBaseStyle, then reproduce the issue in a WPF project using the provided ListBox/ListView steps and an Image child. Compare behavior when list items extend beyond the visible area, and consider the reported BadgeBaseStyle lines 17-26 as the key investigation point; done means the nested Badge renders without a ControlTemplate/Border error.
