SwiftUI bug: Refresh logic of List is invalid in this case.

SwiftUIBug.swift

import SwiftUI


/// This demo shows a bug of SwiftUI. It's related to the refresh logic of "List"
///
/// The steps are:
/// 1. click "Go to next page"
/// 2. click "Click Me"
/// 3. Go back to home page
/// 4. The top view shows "Off", by right it should be "On".
///
/// If remove Section or replace List with ScrollView, the bug is gone.
///
/// I am using Xcode 14.3, Swift 5, Apple M2 Max
/// This bug can be reproduced on both iOS 16.6 (iPhone 8 plus) and Xcode Canvas
