  <p>Item at top offset, this is what i want to do while fast scrolling.</p>
  
  <p>This can do scroll at top: <code>scrollToPositionWithOffset(position, 0)</code>, but it is manual trigger by code.</p>
  
  <p>I want this with the scrollbar.</p>
  
  <p>I have tried using LinearSnapHelper, but that didn't helped with Scrollbar.</p>
  
  <p>I'm using Room and Paging Library to load data lazily.</p>
  
  <p>Thanks.</p>
