FluidMoveBehavior 是否可以与 ContentPresenter 配合使用，或者我是否遇到了 Silverlight 4 中的已知限制？

Question

我创建了一个自定义 ToggleButton，其中内容是手动粘贴到 XAML 中正确位置的 TextBlock（不仅仅是字符串）。 ToggleButton 中的父布局是一个具有 2 列的网格，其中切换会在列之间交换 ContentPresenter 和一些图形。

当 FluidMoveBehavior 按钮打开时（我使用的是 Expression Blend），图形动画完美，但 ContentPresenter 内的 TextBlock 会跳转而没有任何动画。

不知道为什么会发生这种情况，是否有任何我不知道的已知限制？

编辑：添加不稳定行为的 XAML 示例

注意：自问题提出以来，我所做的事情略有不同，但仍然有兴趣知道为什么会发生这种情况，因此隔离了有问题的按钮。
