为什么这个WPF TreeViewItem样式导致交叉线程问题？

我有以下样式应用于treeviewitem容器 . 基本上，用于覆盖选择颜色：

<Style x:Key="element-designer-node-host" TargetType="{x:Type TreeViewItem}">
    <Style.Resources>
        <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" 
                         Color="{DynamicResource nav-tvi-sel-bg1}" />
        <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" 
                         Color="{DynamicResource nav-tvi-sel-bg1}" />
        <SolidColorBrush x:Key="{x:Static SystemColors.InactiveSelectionHighlightBrushKey}" 
                         Color="{DynamicResource nav-tvi-sel-bg2}" />
    </Style.Resources>
    <Setter Property="IsExpanded" Value="{Binding Expanded, Mode=TwoWay}" />
    <Setter Property="IsSelected" Value="{Binding Selected, Mode=TwoWay}" />
</Style>

应用于树视图：

<TreeView
    ItemContainerStyle="{StaticResource element-designer-node-host}"
    ItemsSource="{Binding Nodes}">

现在，我在一个新线程中用这个树视图启动一个窗口，一切正常 .

在该窗口关闭后，我在一个全新的线程中启动全新窗口，当我尝试单击某个节点时，我得到异常：

为什么会发生这种情况，解决方案是什么？

Note that when I remove those three brush overrides from style resources, the problem does not occur.
