silverlight - FluidMoveBehavior 是否可以与 ContentPresenter 一起使用，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，其中的内容是手动粘贴到 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 Grid，其中切换会在列之间交换 ContentPresenter 和一些图形。

当 FluidMoveBehavior 按钮打开时，图形动画完美（我正在使用 Expression Blend），但 ContentPresenter 中的 TextBlock 跳转时没有任何动画。

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：添加异常行为的 XAML 示例

注意：自从提出问题以来，我做的事情略有不同，但仍然想知道为什么会发生这种情况，因此隔离了有问题的按钮。
