onActivityResult() not called in new nested fragment API
<p>I have been using the new <a href="http://developer.android.com/about/versions/android-4.2.html#NestedFragments" rel="nofollow">nested fragment</a> API that Android includes in the support library.</p>

<p>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 <code>FragmentManager</code>returned by <code>getChildFragmentManager()</code>) calls <code>startActivityForResult()</code>, the nested fragment's <code>onActivityResult()</code> method is not called. However, both the parent fragment's <code>onActivityResult()</code> and activity's <code>onActivityResult()</code> do get called.</p>

<p>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:</p>
