CommunityToolkit.WinUI.Animation 显示BUG

[BlameTwo]

Describe the bug

Frame出现了两个Page，如图

PunishV2GamePage中使用了透明度动画，如下：

<ani:Implicit.ShowAnimations>
    <ani:OpacityAnimation To="1" Duration="0:0:0.3" />
</ani:Implicit.ShowAnimations>
<ani:Implicit.HideAnimations>

    <ani:OpacityAnimation To="0" Duration="0:0:0.3" />
</ani:Implicit.HideAnimations>

当我删除这个动画组件的时候，Frame导航变得正常起来，元素树中也没有了元素。

Steps to reproduce

我得时间有限，我也不确定重新创建一个应用是否能够重现此BUG，但请注意这个BUG。

更为匪夷所思的是，同一份二进制在两个Windows PC上出现了两个不同的结果，系统版本号都一致。

Expected behavior

他应该销毁旧页面，而不是重叠。
