title: SimpleDraweeView rounded inside scrollview
body: <p>I'm trying to migrate from UIL to Facebook's Fresco lib. So far everything looks fine but when I put a rounded image inside an scrollview I get a weird behaviour: While scrolling to the bottom, the image overlaps the action bar and it keeps there when I go up.</p>

  <p>this is my code:</p>
  
  <pre><code>            &lt;com.facebook.drawee.view.SimpleDraweeView
                  android:id="@+id/img_item_detail_avatar"
                  android:layout_width="70dp"
                  android:layout_height="70dp"
                  android:layout_gravity="center_vertical|right"
                  fresco:actualImageScaleType="centerCrop"
                  fresco:placeholderImage="@drawable/icn_avatar_mini"
                  fresco:roundAsCircle="true"
                  fresco:viewAspectRatio="1" /&gt;
  </code></pre>
  
  <p>Also, I'm experiencing the same behaviour inside ListViews. Have you had a similar issue? How can I solve it?</p>
