Luis Dialog Sample doesn't wait for user input

Question

so I'm trying to call a different dialog from my luis dialog. When I do this, I expect the luis dialog to wait until the other dialog has finished.

Since I cannot show you my real project, I've used the Luis Dialog Sample to reproduce my problem. I've added another step to the PromptWaterfallDialog which looks like this now:

public PromptWaterfallDialog()
        : base(nameof(PromptWaterfallDialog))
    {
        // This array defines how the Waterfall will execute.
        var waterfallSteps = new WaterfallStep[] // 20190813 FPI diese Schritte werden jedes Mal ausgeführt wenn ein PromptWaterfallDialog aufgerufen wird
        {
            this.AskQuestionStepAsync,
            this.ReturnResultStepAsync,
            this.TestStepAsync
        };

        // Add named dialogs to the DialogSet. These names are saved in the dialog state.
        this.AddDialog(new WaterfallDialog(nameof(WaterfallDialog), waterfallSteps));
        this.AddDialog(new TextPrompt(nameof(TextPrompt)));

        // The initial child Dialog to run.
        this.InitialDialogId = nameof(WaterfallDialog);
    }

    private async Task<DialogTurnResult> AskQuestionStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        var options = stepContext.Options as PromptDialogOptions;
        return await stepContext.PromptAsync(nameof(TextPrompt), new PromptOptions { Prompt = MessageFactory.Text(options.Prompt) }, cancellationToken);
    }

    private async Task<DialogTurnResult> ReturnResultStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        return await stepContext.PromptAsync(nameof(TextPrompt), new PromptOptions { Prompt = MessageFactory.Text("Hi") }, cancellationToken);
    }

    private async Task<DialogTurnResult> TestStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        var options = stepContext.Options as PromptDialogOptions;
        options.Result = stepContext.Result as string;

        await stepContext.Context.SendActivityAsync(MessageFactory.Text("This is just a test"));

        return await stepContext.EndDialogAsync(new DialogTurnResult(DialogTurnStatus.Complete, options));
    }

As you can see, I've added the TestStepAsync. I would expect the dialog to go like this:

1. Bot: PromptMessage (AskQuestionStepAsync)

2. User: some answer ...

3. Bot: Hi (ReturnResultStepAsync)

4. User: some input...

5. Bot: This is just a test (TestStepAsync)

But apparently, the bot skips waiting for the second user input and goes straight to the TestStepAsync as you can see here:

Does anyone know if this kind of behavior is intented or not? And how do I get the bot to work like I expect it to do?

I'm using the Bot Emulator version 4.6.0.

Instead of

Prompt = MessageFactory.Text("Hi")

change it to:

Prompt = MessageFactory.Text("Hi", InputHints.ExpectingInput);
