ListViewItemPresenter background has extra margin

Describe the bug

Background of ListViewItemPresenter rendered with additional spaces. However, content uses the entire area of the presenter.

Reproduced on WindowsAppSDK 1.0.0. Normal on 0.8.*

Steps to reproduce the bug

Xaml:

<Grid Background="LightGray">
   <ListView SelectionMode="None">
      <ListView.ItemContainerStyle>
         <Style TargetType="ListViewItem">
            <Setter Property="BorderBrush" Value="Black" />
            <Setter Property="BorderThickness" Value="0, 0, 0, 1" />
            <Setter Property="Background" Value="DimGray" />
            <Setter Property="Template">
               <Setter.Value>
                  <ControlTemplate TargetType="ListViewItem">
                     <ListViewItemPresenter Background="{TemplateBinding Background}"
                                            BorderBrush="{TemplateBinding BorderBrush}"
                                            BorderThickness="{TemplateBinding BorderThickness}" />
                  </ControlTemplate>
               </Setter.Value>
            </Setter>
         </Style>
      </ListView.ItemContainerStyle>
      <ListView.ItemTemplate>
         <DataTemplate>
            <Border>
               <TextBlock Text="{Binding}" />
            </Border>
         </DataTemplate>
      </ListView.ItemTemplate>
      <x:String>11111</x:String>
      <x:String>22222</x:String>
      <x:String>33333</x:String>
      <x:String>44444</x:String>
      <x:String>55555</x:String>
   </ListView>
</Grid>

Expected behavior

If set background directly to DataTemplate:

<ListView.ItemTemplate>
   <DataTemplate>
      <Border Background="DimGray">
         <TextBlock Text="{Binding}" />
      </Border>
   </DataTemplate>
</ListView.ItemTemplate>

I filed https://stackoverflow.com/questions/74221139/remove-listviewitempresenter-border-in-microsoft-ui-xaml-listview before finding this bug report.

As reported there, there appears to be an additional Border element as a child of the ListViewItemPresenter, and it has a Margin of 4,2,4,2.

I’m very interested in knowing if there’s a way to remove this margin, since it has caused our dozens and dozens of ListViews to render improperly.

Does anyone have a workaround for this?
