title: Cannot Combine Custom Title With Other Title Features
body: <p>I understand what the error is telling me, but I have no idea what I could be using that it considers title features that I'm trying to combine with Custom Title.</p>
  
  <p>inspection_title.axml</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
    &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android"
     android:id="@+id/inspectionTitle"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"
     android:ellipsize="marquee"
     android:marqueeRepeatLimit="-1"/&gt;
  </code></pre>
  
  <p>LiftInspection.cs</p>
  
  <pre><code>[Activity(ScreenOrientation = Android.Content.PM.ScreenOrientation.Portrait)]
  public class LiftInspection : ExpandableListActivity
  {       
      protected override void OnCreate(Bundle bundle)
      {
          base.OnCreate(bundle);
  
          string callInfo = Intent.GetStringExtra("CallInfo");           
  
          RequestWindowFeature(WindowFeatures.CustomTitle);
          SetContentView(Resource.Layout.LiftInspection);
          Window.SetFeatureInt(WindowFeatures.CustomTitle, Resource.Layout.inspection_title);
  
          TextView title = (TextView) FindViewById(Resource.Id.inspectionTitle);
          title.Text = callInfo;
      }
  </code></pre>
  
  <p>There is no additional title customization in the manifest or anything.  What could possibly be combining with the CustomTitle to generate this exception?</p>
