AvalonDock DocumentHeaderTemplate 不适用于浮动 Windows

Question

在 AvalonDock 中，我们使用 LayoutDocumentExtended 在标题中添加一些 AdditionalInformation（不仅仅是我们项目中的字符串）。

在此测试代码中，我们将 DocumentHeaderTemplate 设置如下。

   <xcad:DockingManager.DocumentHeaderTemplate>
    <DataTemplate DataType="{x:Type local:LayoutDocumentExtended}">
      <StackPanel Orientation="Horizontal">
        <TextBlock Text="{Binding Title, StringFormat={}{0} ---- }" />
        <TextBlock Text="{Binding AdditionalString}" />
      </StackPanel>
    </DataTemplate>
  </xcad:DockingManager.DocumentHeaderTemplate>
    <xcad:LayoutRoot>
      <xcad:LayoutPanel Orientation="Vertical" >
        <xcad:LayoutDocumentPane>
          <xcad:LayoutDocumentPane.Children>
            <local:LayoutDocumentExtended Title="Test1" AdditionalString="848451">  </local:LayoutDocumentExtended>
            <local:LayoutDocumentExtended Title="Test2" AdditionalString="1"></local:LayoutDocumentExtended>
          </xcad:LayoutDocumentPane.Children>
        </xcad:LayoutDocumentPane>
    </xcad:LayoutPanel>
  </xcad:LayoutRoot>

如果我将 LayoutDocument 取消停靠为 FloatingWindow，则只会显示 Title 而不会显示 AdditionalString。一旦我再次重新停靠它，AdditionalString 就会再次显示。有人知道如何在 FloatingWindows 上设置可配置的 DocumentHeaderTemplate 吗？

LayoutDocumentFloatingWindowControl控件使用WindowChrome定义标题栏。您可能想修改 chrome 的标题栏以允许它显示额外的垂直内容，即额外的行。或者，考虑在括号中和同一行中显示额外信息。

覆盖 DocumentTitleTemplate 以布局标题：

<DataTemplate x:Key="DocumentTitleTemplate">
  <TextBlock Text="{Binding Title}"
             TextTrimming="CharacterEllipsis">
  </TextBlock>
</DataTemplate>

覆盖LayoutDocumentFloatingWindowControl样式修改标题栏高度：

  <Style x:Key="{x:Type avalonDockControls:LayoutDocumentFloatingWindowControl}"
         TargetType="{x:Type avalonDockControls:LayoutDocumentFloatingWindowControl}">
    <Setter Property="Background"
            Value="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" />
    <Setter Property="BorderBrush"
            Value="{DynamicResource {x:Static SystemColors.ControlDarkBrushKey}}" />
    <Setter Property="BorderThickness"
            Value="3" />
    <Setter Property="shell:WindowChrome.WindowChrome">
      <Setter.Value>
        <shell:WindowChrome ResizeBorderThickness="10"

                            GlassFrameThickness="0"
                            ShowSystemMenu="False" />
      </Setter.Value>
    </Setter>
    <Setter Property="Template">
