Xaml 按钮点击不是第一次被解雇[仅限windows 8.1/10平板电脑]

我正在编写一个带有3个状态按钮（正常、聚焦和按下）的windows通用应用程序示例

我的代码如下所示

现在我面临一个关于按钮点击的问题，当第一次按钮点击时，按钮点击事件并没有被触发。但在第一次点击后，它工作正常[问题只发生在windows平板电脑上，在台式机和笔记本电脑上工作正常]

这是已知的问题，还是我的代码有问题

删除了ObjectAnimationUsingKeyFrames标记，并使用了DoubleAnimation标记。还将目标属性源更改为不透明。然后在指定的持续时间内使用更新图像

<VisualState x:Name="Normal">
   <Storyboard>
     <DoubleAnimation Duration="0" To="1" Storyboard.TargetProperty="Opacity" Storyboard.TargetName="NormalButton"/>
   </Storyboard>
</VisualState>

Set=按下按钮。我们试过了。但是没有按预期工作，真的吗？嗯，没想到的是，稍后我们将不得不回到这一点来仔细观察，对此表示抱歉。
