CarouselView Renders Duplicate Data Templates Multiple Times

Description

When running the Maui Samples, the CarouselView renders Monkey instances multiple times. In MonkeysViewModel.CreateMoneyCollection the code is loading 17 Monkey objects into Monkeys, an ObservableCollection of Monkey. However, the CarouselView is showing many more items than 17, duplicating the original 17 multiple times. Here's the URL to the solution in the maui-samples repository:

https://github.com/dotnet/maui-samples/tree/main/6.0/UserInterface/Views/CarouselViewDemos

I ran into this problem with my code and verified that it reproduces with the maui-samples solution too.

Steps to Reproduce

1. Clone maui-samples
2. Run the carousel demo at https://github.com/dotnet/maui-samples/tree/main/6.0/UserInterface/Views/CarouselViewDemos
3. Select Horizontal Data Template
4. Observe the duplicated templates.

Hi @JoeMayo - Can you try setting Loop="False" and letting us know if that resolves your issue? (Loop="True" by default)

@rachelkang Sorry, I added the Loop="False" attribute to the CarouselView, but no change for me.
