[Feature request]希望TabContrl使用绑定的TableItem可以通过ShowCloseButton关闭

使用场景如下：
某些TabItem我需要在首项显示，且固定不可关闭。
通过如下代码结构
<hc:TabControl> <hc:TabItem ShowCloseButton="False" Header="Home"/> <hc:TabItem ShowCloseButton="True" Header="TabItem1"/> </hc:TabControl>
但是通过绑定的方式，却不能实现
<hc:TabControl IsAnimationEnabled="True" ShowCloseButton="True" ShowOverflowButton="True" IsScrollable="True" ItemsSource="{Binding OpenMainMenuList}" SelectedItem="{Binding CurrentSelectedMainMenu}"> <hc:TabControl.ItemTemplate> <DataTemplate> <Grid hc:TabItem.ShowCloseButton="False"> <Grid.ColumnDefinitions> <ColumnDefinition Width="auto" MinWidth="24"/> <ColumnDefinition/> </Grid.ColumnDefinitions> <TextBlock Grid.Column="1" Text="{Binding TargetControlTitle}" TextTrimming="CharacterEllipsis"></TextBlock> </Grid> </DataTemplate> </hc:TabControl.ItemTemplate> <hc:TabControl.ContentTemplate> <DataTemplate> <hc:ScrollViewer Background="{DynamicResource MainWindowContentForegroundDrawingBrush}"> <ContentPresenter Name="PresenterMain" Content="{Binding TargetContrlObject}"/> <!--<TextBlock Text="{Binding Name}"/>--> </hc:ScrollViewer> </DataTemplate> </hc:TabControl.ContentTemplate> </hc:TabControl>

Start by locating the TabControl and its item-generation logic, then inspect how the ItemTemplate applies hc:TabItem.ShowCloseButton to bound items. Verify the behavior with an ItemsSource containing both fixed and closable tabs; done means each bound item can control its own close-button visibility while the control-level default remains supported.
