ios - SwiftUI - NavigationLink cell in a Form stays highlighted after detail pop

In iOS 14, it appears that NavigationLinks do not become deselected after returning in a Form context. This is also true for Form Pickers and anything else that causes the presentation of another View from a list (giving a highlight context to the presenting cell).

I didn't notice this behaviour in iOS 13.

Is there a way to 'deselect' the highlighted row once the other view is dismissed?

Example code:

struct ContentView: View {

    var body: some View {
        Form {
            NavigationLink(destination: Text("Detail")) {
                Text("Link")
            } 
        }
    }

}

In my case this behaviour appeared when using any Viewcontent (e.g. Text(), Image(), ...) between my NavigationView and List/Form.

var body: some View {
    
    NavigationView {
        VStack {
            Text("This text DOES make problems.")
            List {
                NavigationLink(destination: Text("Doesn't work correct")) {
                    Text("Doesn't work correct")
                }
            }
        }
    }
}

Putting the Text() beneath the List does not make any problems:

var body: some View {
    
    NavigationView {
        VStack {
            List {
                NavigationLink(destination: Text("Does work correct")) {
                    Text("Does work correct")
                }
            }
            Text("This text doesn't make problems.")
        }
    }
}

This is definitely a XCode 12 bug. As more people report this, as earlier it gets resolved.
