NavigationView Bug

Describe the bug

Set the SelecteItem of NavigationView to {get; set;}
When I implement multilingual switching now, when I reload the specified language, the selection of any method does not take effect, and can only take effect through the control's name Navigate on the first attempt

As soon as I switched languages, I reassigned the new object to MenuItem Source to achieve language switching

When switching languages and rewriting to load new menu items, I set the corresponding TYPE through Navigate to not take effect,
If I can put out SelecteItem, I can manually bind it to customize the selection,
Otherwise, the control name will have to be used for the first selection every time, and multiple selections cannot be set

Just to declare, I only used the NavigationView control. If the control can be detached from the architecture, it will be more flexible to use

Also, NavigationView AutoSuggestBox is not working for some unknown reason

To Reproduce

    <menu:NavigationView.AutoSuggestBox>
        <menu:AutoSuggestBox Margin="8,0,8,8" PlaceholderText="{lang:Loc 搜索}" />
    </menu:NavigationView.AutoSuggestBox>

</menu:NavigationView>

Expected behavior

If the selected items can be bound, the selected problem can be solved, but the AutoSuggestBox problem is unknown because only the control was used without any code operation

Additional context

No response

Start by reproducing the reported behavior with the provided WPF NavigationView markup, focusing on MenuItemsSource, language switching, and the AutoSuggestBox. Inspect the NavigationView and AutoSuggestBox entry points to determine whether selected-item binding and search behavior are supported. Done means the selection can be controlled after menu replacement and the reported AutoSuggestBox behavior is understood or fixed.
