translationTask does not execute when content appears

The documentation for translationTask(source:target:action:) says it should translate when content appears, but this isn't happening. I’m only able to translate when I manually associate that task with a configuration, and instantiate the configuration.

Here’s the complete source code:

import SwiftUI
import Translation

struct ContentView: View {

    @State private var originalText = "The orange fox jumps over the lazy dog"

    @State private var translationTaskResult = ""
    @State private var translationTaskResult2 = ""

    @State private var configuration: TranslationSession.Configuration?

    var body: some View {
        List {
        	// THIS DOES NOT WORK
            Section {
                Text(translationTaskResult)
                    .translationTask { session in
                        Task { @MainActor in
                            do {
                                let response = try await session.translate(originalText)
                                translationTaskResult = response.targetText
                            } catch { print(error) }
                        }
                    }
            }

			// THIS WORKS
            Section {
                Text(translationTaskResult2)
                    .translationTask(configuration) { session in
                        Task { @MainActor in
                            do {
                                let response = try await session.translate(originalText)
                                translationTaskResult2 = response.targetText
                            } catch { print(error) }
                        }
                    }

                Button(action: {
                    if configuration == nil {
                        configuration = TranslationSession.Configuration()
                        return
                    }
                    configuration?.invalidate()
                }) { Text("Translate") }
            }
        }
    }
}

How can I automatically translate a given text when it appears using the new translationTask API?
