SwiftUI Hierarchical List on macOS represents incorrect results.

A item is replaced by the last uncle.

1. Target to macOS

2. The item "X" is placed next to the folded sibling with children.

3. The parent of the "X" is not the last sibling.

4. The last uncle "Y" has no children.

Code Block swift
import SwiftUI
struct TreeViewTest: View {
    var items: [Item]
    var body: some View {
        List(
            items,
            children: \.children
        ) { item in
            Text(item.id)
        }

• Is there anything wrong with my code?

• If it is a bug, is there a temporary hacky workaround?
