UWP删除ToggleButton鼠标并鼠标按下背景

Question

UWP：如何删除ToggleButton的鼠标悬停和鼠标按下背景？

XAML：

（PS：这适用于Button！）

    <Style TargetType="ToggleButton">
        <Setter Property="Foreground" Value="White"/>
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ToggleButton">
                    <Grid x:Name="RootGrid" Background="{TemplateBinding Background}">
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal">
                                </VisualState>
                                <VisualState x:Name="PointerOver">
                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <ContentPresenter 
                            x:Name="ContentPresenter"
                            BorderBrush="Transparent"
                            BorderThickness="{TemplateBinding BorderThickness}"
                            Content="{TemplateBinding Content}"
                            ContentTransitions="{TemplateBinding ContentTransitions}"
                            ContentTemplate="{TemplateBinding ContentTemplate}"
                            Padding="{TemplateBinding Padding}"
                            HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"
                            VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
                            AutomationProperties.AccessibilityView="Raw"
                            Foreground="White"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

结果（注意周围的黑色方块和背景稍暗的背景）：

同一个按钮的另一个图像，但随后检查，也许更好看它看起来多么可怕。

下面的例子很好用：

        <Style x:Key="NakedToggleButton"  TargetType="ToggleButton">
            <Setter Property="Background" Value="{ThemeResource SystemControlBackgroundBaseLowBrush}" />
            <Setter Property="Foreground" Value="{ThemeResource SystemControlForegroundBaseHighBrush}"/>
            <Setter Property="BorderBrush" Value="{ThemeResource SystemControlForegroundTransparentBrush}" />
            <Setter Property="BorderThickness" Value="{ThemeResource ToggleButtonBorderThemeThickness}" />
            <Setter Property="Padding" Value="8,4,8,4" />
            <Setter Property="HorizontalAlignment" Value="Left" />
            <Setter Property="VerticalAlignment" Value="Center" />
            <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}" />
            <Setter Property="FontWeight" Value="Normal" />
            <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}" />
            <Setter Property="UseSystemFocusVisuals" Value="True" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ToggleButton">
                        <Grid x:Name="RootGrid" Background="Transparent">
