iOS 13.4 beta: onDrop doesn’t work with List or Views inside it

I am trying to use the new onDrop feature of iOS13.4. It works for me on Stacks, Text views, Buttons and such.

However onDrop is not called on a List, or any views (for instance a custom row view, or a button) when they are inside of a list.

This seems like a bug?

Ultimately, what I want to do is drag something from a DetailView, onto a particular row in a List inside a NavigationView, and have it added to the model associated with that row / detail view, but I can't if the List is swallowing the onDrop calls.

in this code you can drag "Test Person" (PersonRow) onto the VStack, registers fine, onto "Another Test Person" (PersonRow) and that registers find, but you cannot drop onto the List itself or the PersonRows inside the List.

            Image(systemName: "person.circle")
            Text(person.name)

        .onDrag {
            let item = NSItemProvider(object: NSString(string: self.person.name))
            item.suggestedName = self.person.name
            print("onDrag: \(item)")
            return item

struct MyView : View {
    var people: [Person] = [Person(name: "George"), Person(name: "The Kurruth"), Person(name: "The Other")]
    @State var targeted: Bool = true

    var body: some View {
        VStack {
            Text("Test")
            Text("")
            PersonRow(person: Person(name:"Test Person"))
            Text("---------------------")
            PersonRow(person: Person(name:"Another Test Person"))

            //List() {
                ScrollView() {
                ForEach(people) { person in
                    PersonRow(person: person)
                }
            }
            .onDrop(of: ["public.utf8-plain-text"], isTargeted: self.$targeted) { item in
                DispatchQueue.main.async {
