我在C＃wpf应用程序中实现avalon扩展坞，我注意到了奇怪的行为。我正在使用xceed AvalonDock 3.4
通过序列化在应用启动时实现布局保存/加载后，我注意到当我将LayoutAnchorable元素从垂直拖动到水平（反之亦然）时，新的layoutPanel出现在我的LayoutDocument周围。
XML示例和代码如下。我很粗鲁，我做错了什么。当我在avalonDock 2.0中使用相同的代码时，它可以工作，并且没有出现备用的LayoutPanel，但是我认为即使使用新的avalondock，它也应该可以工作。
在首次启动应用后，Layou xml导出看起来像（对我来说似乎还可以）
<LayoutRoot>
<RootPanel Orientation="Vertical">
<LayoutPanel Orientation="Horizontal">
<LayoutDocumentPane>
<LayoutDocument Title="level" IsSelected="True" IsLastFocusedDocument="True" ContentId="level" CanClose="False" LastActivationTimeStamp="10/25/2018 20:11:41" />
</LayoutDocumentPane>
</LayoutPanel>
<LayoutAnchorablePane Name="ToolsPane" DockHeight="25">
<LayoutAnchorable AutoHideMinWidth="100" AutoHideMinHeight="100" Title="Nodes" IsSelected="True" ContentId="nodes" CanClose="False" />
<LayoutAnchorable AutoHideMinWidth="100" AutoHideMinHeight="100" Title="Properties" ContentId="properties" CanClose="False" />
</LayoutAnchorablePane>
</RootPanel>
<TopSide />
<RightSide />
<LeftSide />
<BottomSide />
<FloatingWindows />
<Hidden />
</LayoutRoot>
但是当我将LayoutAnchorable拖动到另一侧时，出现LayoutPanel。当我多次拖动LayoutAnchorable时，会出现多个LayoutPanels。
<LayoutRoot>
<RootPanel Orientation="Horizontal">
<LayoutPanel Orientation="Vertical">
<LayoutPanel Orientation="Horizontal">
<LayoutDocumentPane>
<LayoutDocument Title="level" IsSelected="True" IsLastFocusedDocument="True" ContentId="level" CanClose="False" LastActivationTimeStamp="10/25/2018 20:12:38" />
</LayoutDocumentPane>
</LayoutPanel>
</LayoutPanel>
<LayoutAnchorablePaneGroup Orientation="Horizontal" DockWidth="392" DockHeight="79" FloatingWidth="794" FloatingHeight="89" FloatingLeft="559" FloatingTop="422">
<LayoutAnchorablePane DockHeight="79" FloatingWidth="794" FloatingHeight="89" FloatingLeft="559" FloatingTop="422">
<LayoutAnchorable AutoHideMinWidth="100" AutoHideMinHeight="100" Title="Nodes" IsSelected="True" ContentId="nodes" FloatingLeft="559" FloatingTop="422" FloatingWidth="794" FloatingHeight="89" CanClose="False" LastActivationTimeStamp="10/25/2018 20:12:38" />
<LayoutAnchorable AutoHideMinWidth="100" AutoHideMinHeight="100" Title="Properties" ContentId="properties" FloatingLeft="559" FloatingTop="422" FloatingWidth="794" FloatingHeight="89" CanClose="False" />
</LayoutAnchorablePane>
</LayoutAnchorablePaneGroup>
</RootPanel>
<TopSide />
<RightSide />
<LeftSide />
<BottomSide />
<FloatingWindows />
<Hidden />
</LayoutRoot>

我非常确定它与序列化无关，并且在拖动后立即显示LayoutPanels，但是请确保我将代码附加到序列化中
