List with children on macOS 11.0 renders wrong data

I need to display the following data as a list with groups
Code Block
- Item 00
- Item 01
- Item 10
- Item 20
- Item 21
- Item 11
- Item 02


However if Item 10 is collapsed Item 11 is shown as Item 02.
What am I doing wrong? Unique IDs are set.

You can see it clearly on screenshots:

Correct

The code:
Code Block Swift
import SwiftUI
struct ContentView: View {
   
  let data = Item.getSampleData()
   
  var body: some View {
    List(data, id: \.id, children: \.children) { item in
      Text(item.name)
    }.listStyle(SidebarListStyle())
  }
}
struct ContentView_Previews: PreviewProvider {
  static var previews: some View {
    ContentView()
  }
}
struct Item: Codable {
   
  let id: UUID
  let name: String
  let children: [Item]?
   
  init(id: UUID = UUID(), name: String, children: [Item]? = nil) {
    self.id = id
    self.name = name
    self.children = children
  }
   
  static func getSampleData() -> [Item] {
    [
      Item(name: "Item 00"),
      Item(
        name: "Item 01",
        children: [
          Item(
            name: "Item 10",
            children: [
              Item(name: "Item 20"),
              Item(name: "Item 21"),
            ]
          ),
          Item(name: "Item 11"),
        ]
      ),
      Item(name: "Item 02"),
    ]
  }
   
}


I created a sample project that shows the problem.

I tried it on macOS 11.0.1 and 11.1 Beta
Updated Xcode to 12.3 - same result. OutlineGroup and List with ForEach using recursive view give the same result.

Any help is appreciated.
Exactly the same code works as intended on iOS.

Apple has fixed it, works as intended on macOS 11.5 Beta. Bug #FB8955055

Also works without any problems on macos 12.beta, xcode 13.beta, target ios 15 and macCatalyst 12. Tested on macOS 12 and iPhone ios 15.
