title: Issue with Android Spinner inside RecyclerView items
body: <p>I have an issue with showing RecyclerView elements inside RecyclerView.</p>
  
  <p>When I selected the item inside prelast Spinner(1st pic), the last one (Spinner) disappeared(2nd pic.). What could be the main reason?</p>
  
  <p>Every word is TextView. LayoutManager for inner RecyclerView is FlexboxLayoutManager with FlexDirection.ROW.</p>
