CarouselView ignores CollectionChanged events of source

[Vroomer]

Description

When adding items to the source of CarouselView, the view remains unchanged. The source is ObservableCollection type. Linked IndicatorView does correctly add new indicators, but the corresponding views never appear and can't be swiped/scrolled to. The bug occurs only in Loop="False" mode. Tested on Windows and Android and only Windows seem affected. iOS wasn't tested.

Steps to Reproduce

1. Load the repository and run the app.
2. Click on "Add item".
3. Observe the CarouselView views for changes.

Did you find any workaround?

Seting the ObservableCollection to new instance instead of relying on CollectionChanged event works, but it's not ideal.
