title: Can the tab selection indicator of TabLayout be pinned to the top of the screen while scrolling?
body: <p>I am investigating the way to pin the tab indicator of <code>TabLayout</code> in <code>CoordinatorLayout</code> while scrolling down.</p>
  
  <p>If I add <code>scroll|enterAlwaysCollapsed</code> flag to the <code>TabLayout</code>, then the tablayout itself is dissappeared while scrolling down. I want tab indicator bar be pinned to the top of the screen.</p>
  
  <p>Is there a way to implement this?</p>
