Bug: reveal animation doesn't always start from the search menu item

modify the sample to have more action items on the right of the search menu item, and then click the search menu item. The reveal animation still starts from the most right area, instead of from the search menu item.

Here's an example of the modification that's needed to do it: menu_main.xml

<menu
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:id="@+id/action_search"
        android:icon="@drawable/ic_action_action_search"
        android:title="@string/abc_search_hint"
        app:showAsAction="always"/>
    <item
        android:icon="@android:drawable/ic_menu_edit"
        android:title="edit"
        app:showAsAction="always"/>
</menu>

Please fix this.
