确保箭头键跳过 WPF 菜单中的分隔符项目？

在我的 WPF 菜单中，我有一个分隔符 (System.Windows.Controls.Separator) 项，当通过箭头键导航菜单时，它似乎无形地接受焦点。我希望箭头导航路径能够跳过这些分隔符。我尝试将 IsEnabled 和 IsTabStop 设置为 false，但这些似乎都没有任何效果。

在 XAML 中，如何指定应跳过分隔符项？

更新：这是我的分隔符当前样式的 XAML：

<Style TargetType="{x:Type Separator}">
        <Setter Property="Focusable" Value="false" />
        <Setter Property="SnapsToDevicePixels" Value="true" />
        <Setter Property="IsTabStop" Value="false" />
        <Setter Property="IsHitTestVisible" Value="false" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Separator}">
                    <Border BorderThickness="1" 
                            Margin="10,5,10,5">
                        <Border.BorderBrush>

                            <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1" >
                                <GradientStop Color="{DynamicResource Nui10Color}" Offset="0"/>
                                <GradientStop Color="{DynamicResource Nui50Color}" Offset="1"/>
                            </LinearGradientBrush>

                        </Border.BorderBrush>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

In my WPF menu I have a separator (System.Windows.Controls.Separator) item that seems to invisibly accept focus when navigating the menu via the arrow keys. I'd like the arrow navigation path to skip these separators. I've tried setting IsEnabled and IsTabStop are set to false, but neither of these seem to have any effect.

In XAML, how can I specify that separator items should be skipped?

UPDATE: Here's the currently style XAML for my separator:

<Style TargetType="{x:Type Separator}">
        <Setter Property="Focusable" Value="false" />
        <Setter Property="SnapsToDevicePixels" Value="true" />
        <Setter Property="IsTabStop" Value="false" />
        <Setter Property="IsHitTestVisible" Value="false" />
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="{x:Type Separator}">
                    <Border BorderThickness="1" 
                            Margin="10,5,10,5">
                        <Border.BorderBrush>

                            <LinearGradientBrush StartPoint="0.5,0" EndPoint="0.5,1" >
                                <GradientStop Color="{DynamicResource Nui10Color}" Offset="0"/>
                                <GradientStop Color="{DynamicResource Nui50Color}" Offset="1"/>
                            </LinearGradientBrush>

                        </Border.BorderBrush>
                    </Border>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

我想通了。我需要在 MenuItem 本身而不是模板上设置 Focusable：

<!-- style for menu item separators -->
            <Style TargetType="{x:Type MenuItem}" 
           BasedOn="{StaticResource {x:Type MenuItem}}" 
           x:Key="MenuItemStyleSeparator">
                            <!-- the following line is what I needed -->
                <Setter Property="Focusable" Value="False" />
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type MenuItem}">
                            <Separator IsEnabled="false" />
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>

I figured it out. I needed to set Focusable on the MenuItem itself, not the template:

<!-- style for menu item separators -->
            <Style TargetType="{x:Type MenuItem}" 
           BasedOn="{StaticResource {x:Type MenuItem}}" 
           x:Key="MenuItemStyleSeparator">
                            <!-- the following line is what I needed -->
                <Setter Property="Focusable" Value="False" />
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="{x:Type MenuItem}">
                            <Separator IsEnabled="false" />
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
