title: CardView ignoring android:clipChildren="false"
body: <p>I want to have a CardView which contains an ImageView which overlaps the left border of the CardView.
  I want to do this by giving the ImageView a negative margin.
  This works fine with all other layouts (LinearLayout/RelativeLayout/FrameLayout) by setting clipChildren="false".</p>
  
  <p>However I can't get it to work with a CardView.
  The ImageView will be clipped and does not overlap the CardView.</p>
  
  <pre><code>&lt;android.support.v7.widget.CardView
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_marginLeft="15dp"
          android:clipChildren="false"&gt;
      &lt;ImageView
             android:layout_marginLeft="-10dp"
             android:background="@drawable/some_picture"
             android:layout_width="50dp"
             android:layout_height="50dp"/&gt;
  &lt;/android.support.v7.widget.CardView&gt;
  </code></pre>
