Reordering SwiftUI Sidebar Items Crashes on Big Sur

I'd like to make the items in my sidebar rearrangeable, like Finder, but when I apply the SidebarListStyle it breaks and causes a crash (tested on Big Sur). By removing the style, reordering works as expected. Is there another modifier I should be using? Thanks!

Code Block swift@main
struct MyApp: App {
	var body: some Scene {
		WindowGroup {
			ContentView()
		}
		}
	}
struct ContentView: View {
	@State var strings: [String] = ["A", "B", "C"]
	@State var selection: String?
	var body: some View {
		NavigationView {
			List(selection: $selection) {
				ForEach(strings, id: \.self) { string in
					Text(string)
				}
				.onMove { (indexes, dest) in
					withAnimation {
						self.strings.move(fromOffsets: indexes, toOffset: dest)
					}
				}
			}
			.listStyle(SidebarListStyle())
			VStack {
				Spacer()
				Text(selection ?? "<none>")
					.frame(idealWidth: 100, maxWidth: .infinity, alignment: .center)
				Spacer()
			}
		}
	}
}

Code Block swift
@main
struct MyApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}

struct ContentView: View {

@State var strings: [String] = ["A", "B", "C"]
@State var selection: String?

var body: some View {
NavigationView {
List(selection: $selection) {
ForEach(strings, id: \.self) { string in
Text(string)
}
.onMove { (indexes, dest) in
withAnimation {
self.strings.move(fromOffsets: indexes, toOffset: dest)
}
}
}
.listStyle(SidebarListStyle())
VStack {
Spacer()
Text(selection ?? "<none>")
.frame(idealWidth: 100, maxWidth: .infinity, alignment: .center)
Spacer()
}
}
}
}

I opened Feedback FB7520923 to track the issue too.
