title: Nested Recycler View Scrolling Issue
body: <p>I have used Recycler View Inside Nested Scroll View(which is within CoordinatorLayout):</p>
  
  <pre><code>        &lt;android.support.v4.widget.NestedScrollView
              android:id="@+id/scroll"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              app:layout_behavior="@string/appbar_scrolling_view_behavior"&gt;
  
              &lt;RelativeLayout
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"&gt;
  
                  &lt;android.support.v7.widget.RecyclerView
                      android:id="@+id/sections_recycler_view_linearlayout"
                      android:layout_width="match_parent"
                      android:layout_height="match_parent"
                      android:orientation="vertical" /&gt;
  
              &lt;/RelativeLayout&gt;
  
          &lt;/android.support.v4.widget.NestedScrollView&gt;
  </code></pre>
  
  <p>Within the adapter of above recycler I have added Child Recycler Views programatically using setNestedScrollingEnabled as false. </p>
  
  <p>My Issue is:
  When I am scrolling the child recycler, as soon as its scroll is completed the parent recycler scrolls to top, as if I am setting its adapter again. I have not added any code to notify adapter or to scroll to top-most recycler item or to set adapter again. I could not figure out the reason for this strange behavior.</p>
  
  <p>Any help would be highly appreciated.. !!!</p>
