SwiftUI List Row Items does not respond to click and tap gestuers

Returning from a sheet nither a click or a tap gesture triggers on a component in a list, until you perform a drag gesture.

The best is to see it, so to reproduce the situation I have created a little test. copy and play

Code Block 
import SwiftUI
enum TriggerType: String, CaseIterable {
    case button, tapGesture
}
enum ABC: String, CaseIterable {
    case A,B,C
}
struct ContentView: View {
    @State private var myLetters = [ABC]()
    @State private var triggerType = TriggerType.button
    
    var body: some View {
        List {
            // TriggerType
            Picker(selection: $triggerType, label: Text("no")) {
                ForEach(TriggerType.allCases, id: \.self) { type in
                    Text(type.rawValue)
                }
            }
            .pickerStyle(SegmentedPickerStyle())
            
            // select letter
            LetterPicker(triggerType: $triggerType ,selected: $myLetters)
                .disabled(myLetters.count >= 3)
            
            // view all selected letters
            ForEach(myLetters, id: \.self) { letter in
                MyButton(triggerType: $triggerType, label: letter.rawValue, symbol: "minus.circle.fill", symbolColor: .red) {
                    if let index = myLetters.firstIndex(of: letter) {
                        myLetters.remove(at: index)
                    }
                }
            }
            
            // Information
            Text(Info.text(triggerType: triggerType))
                .padding(EdgeInsets(top: 20, leading: 20, bottom: 50, trailing: 20))

            This is a test to check that a button action or tap gesture triggers
            
            1. \(triggerType == .button ? "Click" : "Tap") on the plus image to add a letter
            
            After adding a letter or two, do not touch the view before step 2
            2. remove a letter by \(triggerType == .button ? "clicking" : "tapping") the minus image
            
            if that removes the letter, Voila! everything is good :). The End
            
            but!
            If nothing happends,  \(triggerType == .button ? "clicking" : "tapping") dose not remove the letter.
            3. Tap and hold anywhere on the screen, then drag down.
            
            4. Go back to step 2.
            
            If now after the draggesture it is possible to remove the letter, well then you expirienced exactly what I did - and that does not work well for me.
