onActivityResult() not called in new nested fragment API

I have been using the new nested fragment API that Android includes in the support library.

The problem that I am facing with nested fragments is that, if a nested fragment (that is, a fragment that has been added to another fragment via the FragmentManagerreturned by getChildFragmentManager()) calls startActivityForResult(), the nested fragment's onActivityResult() method is not called. However, both the parent fragment's onActivityResult() and activity's onActivityResult() do get called.

I don't know if I am missing something about nested fragments, but I did not expect the described behavior. Below is the code that reproduces this problem. I would very much appreciate if someone can point me in the right direction and explain to me what I am doing wrong:

package com.example.nestedfragmentactivityresult;

import android.media.RingtoneManager;
import android.os.Bundle;
import android.content.Intent;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends FragmentActivity
{
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        this.getSupportFragmentManager()
            .beginTransaction()
            .add(android.R.id.content, new ContainerFragment())
            .commit();
    }

    public void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        super.onActivityResult(requestCode, resultCode, data);

        // This is called
        Toast.makeText(getApplication(),
            "Consumed by activity",
            Toast.LENGTH_SHO
