窗口边缘的小型可控区域控件

Question

我正在使用MahApps.Metro 1.3.0并且在窗口边缘有一个较小的可点击控件区域的问题，但如果我将它们从窗口边缘移开，可点击区域会恢复正常

有什么方法可以解决这个问题吗？

我的scrollviewer xaml：

<ScrollViewer x:Name="ScrollViewer" VerticalScrollBarVisibility="Visible" HorizontalScrollBarVisibility="Auto">
<ItemsControl x:Name="DocumentList" ItemsSource="{Binding Source={StaticResource Documents}}" BorderBrush="{x:Null}" ScrollViewer.CanContentScroll="False" Margin="0,0,0,1">
    <ItemsControl.ItemTemplate>
        <DataTemplate>
            <TextBlock>
                <Hyperlink Command="{Binding DataContext.OpenCommand, RelativeSource={RelativeSource AncestorType={x:Type ItemsControl}}}" CommandParameter="{Binding UNID}"> 
                    <InlineUIContainer>
                        <TextBlock Text="{Binding DisplayName}" />
                    </InlineUIContainer>
                </Hyperlink>
            </TextBlock>
        </DataTemplate>
    </ItemsControl.ItemTemplate>

    <ItemsControl.GroupStyle>
        <GroupStyle>
            <GroupStyle.ContainerStyle>
                <Style TargetType="{x:Type GroupItem}">
                    <Setter Property="Template">
                        <Setter.Value>
                            <ControlTemplate>
                                <Expander Header="{Binding Name}" IsExpanded="False">
                                    <ItemsPresenter />
                                </Expander>
                            </ControlTemplate>
                        </Setter.Value>
                    </Setter>
                </Style>
            </GroupStyle.ContainerStyle>
        </GroupStyle>
    </ItemsControl.GroupStyle>
</ItemsControl>
</ScrollViewer>
