title: Nested Recyclerview scrolls by itself
body: <p>I have a parent recyclerview that has 3 child view in it. The last two of the child are recyclerview.</p>
  
  <pre><code>Parent recyclerview
   - child view 1
   - child view 2 (horizontal rv)
   - child view 3 (horizontal rv)
  </code></pre>
  
  <p>The issue is every time this fragment is visible, it scrolls itself to align with <code>child view 2</code>'s bottom.</p>
  
  <p>I have set the parent rv to listen for scroll. This is what I end up with:</p>
  
  <pre><code>dy: 108
  dy: 72
  dy: 75
  dy: 62
  dy: 48
  dy: 42
  dy: 34
  dy: 27
  dy: 22
  dy: 16
  dy: 12
  dy: 10
  dy: 7
  dy: 5
  dy: 3
  dy: 3
  dy: 1
  dy: 1
  dy: 1
  </code></pre>
  
  <p>It seems like the starting <code>dy</code> of parent recyclerview is set to <code>0</code> to the <code>child view 2</code> rv. Everything above it is in -ve value. However, I'm not sure if this was the case as I'm still finding out what causes it.</p>
  
  <p>Any fix?</p>
