CarouselView behaves strangely when manipulating position in ViewModel

[Campfire9263]

Description

As expected, one can manipulate the position of the CarouselView to increase, but decreasing seems to misbehave.
Here a clip to illustrate:

CarouselViewSample.2024-05-16.19-21-17.mp4

Upon debugging to follow the stack of calls, it seems the generated code to set the property bound to the CarouselViewPosition (set_CarouselViewPosition) is called three times in total when increasing, but only two times when decreasing.

Steps to Reproduce

1. Build the repository CarouselViewSample
2. Increase the position at least once
3. Observe the strange behaviour when trying to go down.

I also had this issue. I gave up on CarouselView, on Windows platform it is unusable, also for other important open issues: #18014
