Unable to use transitions for SwiftData in List

I can't for the life of me get transitions and animations to work well with SwiftData and List on MacOS 15 and iOS 18.

I've included an example below, where I define several animations and a transition type, but they are all ignored.

How do I animate items being added to / removed from a List()?

I am attached to List() due to its support for selection, context menu, keyboard shortcuts, etc. If I would switch to ScrollView with VStack I would have to rebuild all of that.

Also, this is super basic and should just work, right?

Thanks for reading.

import SwiftUI
import SwiftData

struct ContentView: View {
    @Environment(\.modelContext) private var modelContext
    
    /// Issues on iOS:
    /// Items animate into and out of view, but I seem to have no control over the animation.
    /// In the code here I've specified a 'bouncy' and a slow 'easeIn' animation: both are not triggered.
    /// The code also specifies using a 'slide' transition, but it is ignored.
    /// -> How do I control the transition and animation timing on iOS?
    ///
    /// Issues on MacOS:
    /// Items do not animate at all on MacOS! They instantly appear and are instantly removed.
    /// -> How do I control the transition and animation timing on MacOS?

    
    // animation added here -> has no effect?
    @Query(animation: .bouncy) private var items: [Item]

    var body: some View {
        VStack {

            Button("Add to list") {
                // called without 'withAnimation' -> no animation
                let newItem = Item(timestamp: Date())
                modelContext.insert(newItem)
            }
            
            List() {
                ForEach(items, id: \.self) { item in
                    Text(item.timestamp, format: Date.FormatStyle(date: .numeric, time: .standard))
                        .transition(.slide) // items do not slide in/out of view
                        .onTapGesture {
                            // called with 'withAnimation' -> no animation
                            withAnimation(.easeIn(duration: 2)) {
                                modelContext.delete(item)
                            }
                        }
                }
                .animation(.spring(duration: 3), value: items)
            }
        }
        .padding()
    }
}

#Preview {
    ContentView()
        .modelContainer(for: Item.self, inMemory: true)
}
