Strange Animation with contentMargins(.training)

ContentView.swift

import SwiftUI

public struct ContentView: View {
    @State var items = [Item]()

    public init() {}

    public var body: some View {
        HStack {
            Button {
                items.append(Item())
            } label: {
                Image(systemName: "plus")
            }
            .frame(width: 50)

            ScrollView {
                VStack {
                    ForEach(items) { item in
                        HStack {
                            Text(item.id.uuidString)
                                .frame(maxWidth: .infinity)
                            Button {
                                items.removeAll { $0.id == item.id }
                            } label: {
                                Image(systemName: "trash.fill")
                            }
                        }
                        .padding()
                        .background(Color(.secondarySystemBackground), in: .rect(cornerRadius: 8))
                    }
                }
                .animation(.default, value: items.map(\.id))
            }
            .contentMargins(.trailing, 100)

            Spacer(minLength: 0)
        }
    }

    struct Item: Identifiable {
        var id = UUID()
    }
}

contentMargins(.trailing)を利用すると、ScrollViewが空っぽになる直前のアニメーションが変になります。
When using contentMargins(.trailing), the animation just before the ScrollView becomes empty looks strange.
