[Windows] KeepLastItemInView Behavior Not Working as Expected in CarouselView

[NafeelaNazhir]

Description

The KeepLastItemInView mode of the ItemsUpdatingScrollMode property in the CarouselView is not functioning as expected on Windows. When the Items are added , the last item in the CarouselView is not kept in view.

• When Loop is false: If the visible content is already at the first position and new items are added , the CarouselView scrolls to the secondlast item instead of the last item. However, if the user scrolls to a certain position and then adding items, the Carouselview correctly scrolls to the last item.
• When Loop is true: When the Items are added , the last item in the CarouselView is not kept in view and the position changes unpredictably.
