ScrollViewReader use bug

This code has a behavior that I think might be a bug, but I wanted to check to see if anyone spots a flaw in my thinking.

This code makes a scrollable containing a single view which itself encapsulated a longer-than-the-screen list. Note the UnitPoint on line 9, the y: component seems to be a percentage.

The bug is that the point requested must be on the screen. In this case, it seems to be around the 12, but with different numbers I get different results.

The only time it seems to be consistent is if the current scroll position is at the very top.

Code Block import SwiftUI
struct ListVsScrollview: View {
		var body: some View {
				NavigationView {
						ScrollViewReader { sv in
								VStack{
										Button("Move") { sv. ;sv.scrollTo(72, anchor: UnitPoint(x: 0.0, y: 0.1)) }
										ScrollView {
												VStack {
														Text("Hi").font(.title)
														ForEach(0...100, id: \.self) { number in
																Text("\(number)").font(.title)
														}
														Text("Low").font(.title)
												}.id(72)
										}
										.navigationBarItems(trailing: EditButton())
								}
						}
				}
		}
}
struct ListVsScrollview_Previews: PreviewProvider {
		static var previews: some View {
				ListVsScrollview()
		}
}
