Issue with observing SwiftData model and UndoManager

I have created a minimum example to demonstrate an issue with observing SwiftData model and UndoManager. This project includes a simple NavigationSplitView, an Item SwiftData model that is being persisted and an enabled UndoManager.

Problem: The SwiftData model Item can be observed as expected. Changing the date in the DetailView works as expected and all related views (ListElementView + DetailView) are updated as expected. When pressing ⌘+Z to undo with the enabled UndoManager, deletions or inserts in the sidebar are visible immediately (and properly observed by ContentView). However, when changing the timestamp and pressing ⌘+Z to undo that change, it is not properly observed and immediately updated in the related views (ListElementView + DetailView).

Further comments:

• Undo operation to the model value changes (here: timestamp) are visible in the DetailView when changing sidebar selections
• Undo operation to the model value changes (here: timestamp) are visible in the ListElementView when restarting the app
• Undo operation to the model value changes (here: timestamp) are are properly observed and immediately visible in the sidebar, when ommiting the ListElementView (no view encapsulation)

Relevant code base:

struct ContentView: View {
    @Environment(\.modelContext) private var modelContext
    @Query private var items: [Item]
	@State private var selectedItems: Set<Item> = []

    var body: some View {
        NavigationSplitView {
			List(selection: $selectedItems) {
                ForEach(items) { item in
					ListElementView(item: item)
						.tag(item)
                }
                .onDelete(perform: deleteItems)
            }
            .navigationSplitViewColumnWidth(min: 180, ideal: 200)
            .toolbar {
                ToolbarItem {
                    Button(action: addItem) {
                        Label("Add Item", systemImage: "plus")
                    }
                }
            }
        } detail: {
			if let item = selectedItems.first {
				DetailView(item: item)
			} else {
				Text("Select an item")
			}
        }
		.onDeleteCommand {
			deleteSelectedItems()
		}
    }

    private func addItem() {
        withAnimation {
            let newItem = Item(timestamp: Date())
            modelContext.insert(newItem)
        }
    }

    private func deleteItems(offsets: IndexSet) {
        withAnimation {
            for index in offsets {
                modelContext.delete(items[index])
            }
        }
    }
	
	private func deleteSelectedItems() {
		for selectedItem in selectedItems {
			modelContext.delete(selectedItem)
			selectedItems.remove(selectedItem)
		}
	}
}

struct ListElementView: View {
	@Bindable var item: Item
	
    var body: some View {
		Text("Item at \(item.timestamp, format: Date.FormatStyle(date: .numeric, time: .standard))")
    }
}

struct DetailView: View {
	@Bindable var item: Item
	
    var body: some View {
		Text(item.timestamp, format: Date.FormatStyle(date: .numeric, time: .standard))
		
		DatePicker(selection: $item.timestamp, label: { Text("Change Date:") })
    }
}

@Model
final class Item {
    var timestamp: Date
    
	init(timestamp: Date) {
        self.timestamp = timestamp
    }
}

It seems that the UndoManager does not trigger a redraw of the ContentView through the items query? Is this a bug or a feature?
