Why pivot will cause crash when clicking and tapping(only Surface not desktop not phone), but swiping works fine in UWP?

问题

I'm upgrading my app to UWP and found that when I swipe the pivot item it works fine while clicking|tapping will cause app crash. This only happens in SP not in desktop mode nor phone. I do think this style is broken, but have no idea why it will fail and how to fix it. Any idea?

    <Style x:Key="PivotStyle" TargetType="Pivot">
        <Setter Property="Margin" Value="0"/>
        <Setter Property="Padding" Value="0"/>
