title: Xamarin.Forms AppCompat MasterDetail no titlebar showing
body: <p>I have a problem with Xamarin.Forms (v2.3)</p>
  
  <p>I followed this guide:
  <a href="https://developer.xamarin.com/guides/xamarin-forms/platform-features/android/appcompat/" rel="nofollow noreferrer">https://developer.xamarin.com/guides/xamarin-forms/platform-features/android/appcompat/</a></p>
  
  <p>And so far I have been able to integrate the Material design successfully in my Forms app.</p>
  
  <p>What is not actually working as I would love to is the MasterDetail, that I am calling from a LoginPage with this line:</p>
  
  <pre><code>await Navigation.PushModalAsync(new HomePage());
  </code></pre>
  
  <p>What is not working can be seen in these screenshots:</p>

  <p>The MasterDetail appers, but the title bar with the title and the hamburger logo do not.
  This is the code that describes my MasterDetail:</p>
  
  <pre><code>&lt;MasterDetailPage
    xmlns="http://xamarin.com/schemas/2014/forms"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    x:Class="MyClassPath"
    Title="Care Page"&gt;
  
    &lt;MasterDetailPage.Master&gt;
      &lt;ContentPage Title="Title"&gt;
        &lt;Label/&gt;
      &lt;/ContentPage&gt;
    &lt;/MasterDetailPage.Master&gt;
  
    &lt;MasterDetailPage.Detail&gt;
      &lt;ContentPage Title="Title"&gt;
        &lt;Label/&gt;
      &lt;/ContentPage&gt;
    &lt;/MasterDetailPage.Detail&gt;
  
   &lt;/MasterDetailPage&gt;
  </code></pre>
