我有以下XAML

<GridView x:Name="DeviceTargets"
            ContainerContentChanging="GridViewContainerContentChanging"
            Grid.Row="1"
            x:DeferLoadStrategy="Lazy"
            Visibility="Collapsed"
            Margin="0 14 0 10"
            IsItemClickEnabled="True"
            ItemClick="OnDeviceTargetsItemClicked"
            ItemContainerStyle="{StaticResource GridViewItemStyleSV}"
            ItemsSource="{x:Bind ViewModel.DeviceList, Mode=OneWay}"
            Padding="0"
            SelectionMode="None"
            ScrollViewer.HorizontalScrollMode="Disabled"
            ScrollViewer.VerticalScrollMode="Disabled">
    <GridView.ItemTemplate>
        <DataTemplate x:DataType="viewModels:DeviceViewModel">
            <local:DeviceItem ViewModel="{x:Bind}"/>
        </DataTemplate>
    </GridView.ItemTemplate>
</GridView>

DeviceItem控件：

<Grid Style="{StaticResource ItemRootGridStyle}">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    
    <local:BadgedPersonPicture
        x:Name="DeviceBadge"
        Grid.Row="0"
        Contact="{x:Bind ViewModel.DeviceContact, Mode=OneWay}" 
        BadgeImageSource="{x:Bind ViewModel.DeviceBadgeImage, Mode=OneWay}" />

    <local:TwoLinesTextBlock
        x:Name="DeviceName"
        Grid.Row="1"
        Text="{x:Bind ViewModel.DeviceDisplayName, Mode=OneWay}" />
</Grid>

BadgedPersonPicture控件：

<Grid Width="64">
    <PersonPicture
        Width="48"
        Height="48"
        HorizontalAlignment="Center"
        Contact="{x:Bind Contact, Mode=OneWay}"
        ProfilePicture="{x:Bind ProfilePicture, Mode=OneWay}" />
    <Ellipse Width="23" Height="23" StrokeThickness="1" Fill="{ThemeResource PersonBadgeBackgroundBrush}"
        HorizontalAlignment="Right" VerticalAlignment="Bottom" />
    <Ellipse Width="23" Height="23" StrokeThickness="1" Stroke="{ThemeResource PersonBadgeBorderBrush}"
        HorizontalAlignment="Right" VerticalAlignment="Bottom">
        <Ellipse.Fill>
            <ImageBrush ImageSource="{x:Bind BadgeImageSource, Mode=OneWay}" Stretch="None"></ImageBrush>
        </Ellipse.Fill>
    </Ellipse>
</Grid>

当我禁用某些GridViewItem时，它显示如下

正如你在红框中看到的，背景中控件的边框正在泄漏到视图中。任何想法，我如何才能使它看起来像一个没有被禁用至于控制在前面和后面的关注？
