Scrolling issue, if the item view is scrollview

[fso-msrl]

because my item content is too long, so I need to add the scrollview in the top level of my content view, like that:

ACarousel(pages) { page in
ScrollView(.vertical) {
VStack{...}
}
}

but if you scroll a little right-down, it will show around 10-20px padding in right side. I already set the space & headSpace to 0
also does not work.

how to fix it?
thanks
