onAppear not called for view in a List in a TabView on WatchOS

For the following code, the "Appeared..." label only gets displayed for the elements that are initially visible, when others are scrolled into view the onAppear does not get called on WatchOS.

It just shows

Code Block Appeared 1
Appeared 2
Appeared 3
Appeared 4
Appeared 5
Not appeared
Not appeared
Not appeared
Not appeared

Code Block
Appeared 1
Appeared 2
Appeared 3
Appeared 4
Appeared 5
Not appeared
Not appeared
Not appeared
Not appeared

... even when the "Not appeared" elements are scrolled into view.

Code Block swiftstruct PagesView : View {
  var body : some View {
    TabView {
      List {
        ForEach(Array(1...10), id: \.self) { v in
          Row(number: v)
        }
      }
    }
  }
}
struct Row : View {
  let number : Int
  @State var label = "Not appeared"
  var body : some View {
    Text(label)
      .onAppear {
        label = "Appeared \(number)"
      }
  }
}

Code Block swift
struct PagesView : View {
var body : some View {
TabView {
List {
ForEach(Array(1...10), id: \.self) { v in
Row(number: v)
}
}
}
}
}

struct Row : View {
let number : Int
@State var label = "Not appeared"
var body : some View {
Text(label)
.onAppear {
label = "Appeared \(number)"
}
}
}

Does anyone know why this might be happening?
