如何在wpf中保存绑定到ObservableCollection的选项卡控件项的Tab键顺序？

<Window x:Class="WpfApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="WPF TabIndex Example" Height="450" Width="800">
    <Grid>
        <TabControl ItemsSource="{Binding Tabs}">
            <TabControl.ItemContainerStyle>
                <Style TargetType="TabItem">
                    <Setter Property="TabIndex" Value="{Binding TabIndex}" />
                </Style>
            </TabControl.ItemContainerStyle>
            <TabControl.ContentTemplate>
                <DataTemplate>
                    <!-- Content of each tab item -->
                </DataTemplate>
            </TabControl.ContentTemplate>
        </TabControl>
    </Grid>
</Window>
