XAML Visual Tree does not represent the underlaying data

[AuderixDev]

Describe the bug

Working with Listview and ListView.ItemTemplate I noticed a strange behaviour.
I debugged it with the Visual Tree Viewer and noticed, that after removing items from the Listview, some items are reappearing in the XAML Visual Tree.
Further interactions with the ListView leads to wrong beahviour, like Loaded-Events are not triggered, because the Item already exists.

Steps to reproduce the bug

MainPage.xaml

...
 <ListView ItemsSource="{Binding NameList}" x:Name="outerList">
   <ListView.ItemTemplate>
     <DataTemplate>
       <StackPanel Orientation="Horizontal" x:Name="innerobject">
         <TextBlock Text="{Binding Id}" />
         <Button Content="Remove"
                 Command="{Binding DataContext.RemoveMe, ElementName=outerList}"
                 CommandParameter="{Binding Id}"/>

       </StackPanel>
       
     </DataTemplate>
    </ListView.ItemTemplate>
 </ListView>
...

MainModel.cs

...
  public IListState<Customer> NameList => ListState<Customer>.Empty(this);

  public async Task AddToList()
  {
      await NameList.AddAsync(new Customer());
  }

  public async Task RemoveMe(Guid id)
  {
      await NameList.RemoveAllAsync(match: x => x.Id == id);
  }

  public partial record Customer()
  {
      public Guid Id { get; } = Guid.NewGuid();
  }
...

Expected behavior

The Visual Tree should represent the underlaying data.

Can you attach the repro app that you have in your repro video?

[AuderixDev]

Here is the repo. As said, It's in Uno. But it only uses normal WinUI controls.
