Rounded corners with drop shadow not rendering correctly on iOS

[experimentalPrivateRepos]

Problem

When trying to use a Drop Shadow + Rounded Corners on iOS in a CarouselView, the corners of the pancake view are not being rendered correctly.

On Android, no shadow is being rendered at all.

                        </CarouselView.ItemTemplate>
                    </CarouselView>

Do you have any idea what might cause this rendering error? Thanks in advance.
