Once the navigation item has been removed, view page is still right there in the RootFrame.

Describe the bug

I made a simple button to add/remove navigation items.
When I remove a item from NavigationItems, that item is quickly removed from the RootNavigation on the left panel.
But the linked page is still showed in RootFrame on the right panel.

To Reproduce

    [RelayCommand]
    private void OpenFLinkFunc()
    {

            foreach (NavigationItem item in NavigationItems)
            {
                if (item.PageTag == "Data")
                {
                    NavigationItems.Remove(item);
                    break;
                }
            }
    }

Expected behavior

According to the focus of Navigation, the linked page should display right page on the right panel.

Additional context

No response

Start by reproducing the issue with the provided NavigationItems removal example on WPF UI 2.0.3, then trace how RootNavigation selection relates to the page displayed in RootFrame. The fix is complete when removing the selected navigation item leaves RootFrame showing the appropriate page instead of the removed item's page.
