SwiftUI List cell stays selected after back navigation

With a navigation hierarchy of more than two layers the NavigationLink in a List or Form will stay selected when navigating back.

Minimal example:

import SwiftUI

struct ContentView: View {
    var body: some View {
        NavigationView {
            List {
                NavigationLink(destination: Form {
                    NavigationLink(destination: Text("Destination")) {
                        Text("Sublink")
                    }
                }) {
                    Text("Link")
                }
            }
        }
    }
}

Go to the lowest level and pop one back → "Sublink" stays highlighted.

It doesn't matter if it's a Form or List, a NavigationLink or Picker, or SwiftUI/UIKit lifecycle. It also doesn't matter if it's split into multiple components or otherwise separated, so to keep the example short everything is inline.

I've found previous questions on this:

• StackOverflow
• Developer Forums 1
• Developer Forums 2

None of the solutions worked for me, but I didn't try force reloading the Lists via .id() as that is really a last resort workaround.

I've also submitted FB9077329 in April, which I haven't had a response to, yet. When i wrote that report I thought this was related to UIKit UINavigationController interoperability (having a mixed hierarchy of ViewControllers and SwiftUI views in the navigation stack), but I can reproduce it with a NavigationView too (as you see in the example).

The screenshot is a slightly modified version of the example above, just with navigationTitles set (doesn't affect the problem, so omitted for brevity).

Edit with some more context: I think this has happened for all of iOS 14 / Xcode 12 and it still happens on iOS 15 / Xcode 13 beta.
