title: react-virtualized combined with WindowScroller and AutoSizer on large list does not render all items
body: <p>I have a large list of more than 300 items. For better preformance I want to use react-virtualized and only render the currently visible items on the screen. For design reasons, I have to use the WindowScroller and depending on the screen size, the list has a different width.</p>
  
  <p>Therefore I'm using WindowScroller and Autosizer. I can scroll down the whole list of 70 items but it stops rendering after 30 list items (which are there before I start scrolling). The number of items rendered depends on the visible space (checked with opened and closed console from codesandbox.io).</p>
  
  <p>I think I have an error in the usage but I don't know what I'm doing wrong.</p>
  
  <p>Full Example: <a href="https://codesandbox.io/s/64lzm266n" rel="nofollow noreferrer">https://codesandbox.io/s/64lzm266n</a></p>
  
  <p>I have searched on stackoverflow and the issues page of react-virtualized but coukd not find a solution. I hope somebody can help me.</p>
