Why doesn't the Background property on the ListViewItem change?

Question

WPF

Hello! In WPF, I made a trigger in the ListView to change the color when the IsMouseOver property is set. But the background and border color does not change. Only the BorderThickness property fires.

<ListView>
            <ListView.ItemContainerStyle>
                <Style TargetType="{x:Type ListViewItem}">
                    <Setter Property="Background" Value="Red"/>
                    <Style.Triggers>
                        <Trigger Property="IsMouseOver" Value="True">
                            <Setter Property="Background" Value="Green" />
                            <Setter Property="BorderBrush" Value="#D80BFC" />
                            <Setter Property="BorderThickness" Value="3" />
                        </Trigger>                    
                </Style.Triggers>
                </Style>
            </ListView.ItemContainerStyle>
            <ListViewItem>
                <TextBlock Text="Item 1"></TextBlock>
            </ListViewItem>
        <ListViewItem>
            <TextBlock Text="Item 2"></TextBlock>
        </ListViewItem>
    </ListView>

In the picture, Item 2 has the state IsMouseOver = True. Only the width of the border has changed, and the color remains the default. Why is it so?

It is necessary to body the ControlTemplate. I do not know why. But it either doesn't work directly, or it doesn't work as it seems.
I'll give you my shortened example:

<Style TargetType="ListViewItem">
    <Setter Property="SnapsToDevicePixels" Value="true" />
    <Setter Property="OverridesDefaultStyle" Value="true" />
    <Setter Property="local:Properties.IsStatus" Value="{Binding IsStatus, Mode=OneWay}" />
    <Setter Property="local:Properties.IsConnection" Value="{Binding IsConnection, Mode=OneWay}" />
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type ListViewItem}">
                <Border
                    x:Name="Border"
                    Background="{TemplateBinding Background}"
                    BorderBrush="{TemplateBinding BorderBrush}">
                    <ContentPresenter
                        x:Name="Content"
                        Margin="0,0,0,0"
                        TextBlock.Foreground="{TemplateBinding Foreground}"
                        HorizontalAlignment="Stretch"
                        VerticalAlignment="Stretch" />
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
