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.
