AVAudioSession.interruptionNotification only delivered once

In my app, I only get one interruption notification when a phone call comes in, and nothing after that. The app uses AVAudioEngine. Is this a bug?

A very simple repro is to just register for the notification, but not do anything else with audio:

struct ContentView: View {

    var body: some View {
        VStack {
            Image(systemName: "globe")
                .imageScale(.large)
                .foregroundStyle(.tint)
            Text("Hello, world!")
        }
        .padding()
        .onReceive(NotificationCenter.default.publisher(for: AVAudioSession.interruptionNotification)) { event in
            handleAudioInterruption(event: event)
        }
    }

    private func handleAudioInterruption(event: Notification) {
        print("handleAudioInterruption")
        guard let info = event.userInfo,
              let typeValue = info[AVAudioSessionInterruptionTypeKey] as? UInt,
              let type = AVAudioSession.InterruptionType(rawValue: typeValue) else {
            print("missing the stuff")
            return
        }
        if type == .began {
            print("interruption began")
        } else if type == .ended {
            print("interruption ended")
            guard let optionsValue = info[AVAudioSessionInterruptionOptionKey] as? UInt else { return }
            if AVAudioSession.InterruptionOptions(rawValue: optionsValue).contains(.shouldResume) {
                print("should resume")
            }
        }
    }
}

And do this in the app's init:

@main
struct InterruptionsApp: App {

    init() {
        try! AVAudioSession.sharedInstance().setCategory(.playback,
                                                         options: [])
        try! AVAudioSession.sharedInstance().setActive(true)
    }

    var body: some Scene {
        WindowGroup {
            ContentView()
        }
    }
}
