title: ImageButton background color with appcompat
body: <p>I've got problems to have a good background from an AppCompatImageButton, just to try I'm comparing this two layouts:</p>
  
  <pre><code>    &lt;android.support.v7.widget.AppCompatImageButton
          android:id="@+id/imageButtonI"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_alignParentEnd="true"
          android:layout_centerVertical="true"
          android:contentDescription="@string/icolor"
          android:tint="@color/accent"
          app:srcCompat="@drawable/magnify"/&gt;
  
      &lt;ImageButton
          android:id="@+id/imageButtonS"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_alignParentEnd="true"
          android:layout_centerVertical="true"
          android:contentDescription="@string/scolor"
          android:tint="@color/accent"
          android:src="@drawable/magnify"/&gt;
  </code></pre>
  
  <p>and the style file:</p>
  
  <pre><code>&lt;style name="AppBaseTheme" parent="android:Theme.Material"&gt;
      &lt;item name="android:colorPrimary"&gt;@color/primary&lt;/item&gt;
      &lt;item name="android:colorPrimaryDark"&gt;@color/primaryDark&lt;/item&gt;
      &lt;item name="android:colorAccent"&gt;@color/accent&lt;/item&gt;
  &lt;/style&gt;
  </code></pre>
  
  <p>As you can see from this image however, the background of ImageButton is "normal" while there isn't any background in the appcompat one. How can I have the "normal" background using <code>AppCompatImageButton</code>?</p>
