Description

If I use a CarouselView and an IndicatorView with an IndicatorTemplate, the IndicatorView wont show anymore if the ItemSource once receives a ItemSource.Count = 0 and gets filled again.

I have made 2 CarouselView+IndicatorView for illustration, one with and one without IndicatorTemplate.

I also tested it on iOS in my original project - it showed the same behavior there.

I added a link to my test project.

Steps to Reproduce

Steps to reproduce:

1. create MAUI App
2. create CarouselView + IndicatorView (incl. IndicatorTemplate)
3. create a MainViewModel with an ObservableCollection Items and initially fill it with Items.Count > 1.
4. Add 2 buttons:

• one for Items.Add()
• one for Items.RemoveAt(index)

5. start the app, delete items with the button until .Count = 0, add an item again and notice that the CarouselView is still displayed, but not the indicatorView.
