This is not a bug.

https://github.com/AvaloniaUI/Avalonia/blob/master/src%2FAvalonia.Controls%2FItemsControl.cs#L497-L543

ItemsControl is designed to behave like this. As long as an element is a control, the container will display the control itself.

If you dont need this feature, you should derive a new class, and override this method according to your needs.

Further more, UserControl as ItemsSource in general is valid but not a good practice
