TabControl 的一个边框的问题

Question

<TabControl Background="Black" BorderThickness="0" Padding="0" Height="200"  Name="tabControl1"  Width="200"  
            <TabItem Header="tabItem1" Name="tabItem1">
                <Grid >
                	<ListBox Background="Black" Foreground="#FFF5E9E9"  >
                		<ListBoxItem>123</ListBoxItem>
				<ListBoxItem>123</ListBoxItem>
				<ListBoxItem>123</ListBoxItem>
                	</ListBox>
		</Grid>
            </TabItem>
</TabControl>

这样设置了 ，请问那个边框，是哪控件的，怎么去掉他，或者换个颜色

是默认模版里面ContentPresenter的产生的么 其他好像都不是。

以下是默认TabControl的Style，请参考。

<SolidColorBrush x:Key="TabControlNormalBorderBrush"
                     Color="#8C8E94"/>
    <Style x:Key="{x:Type TabControl}"
