Repro steps:

  1. open https://stackblitz.com/edit/react-l1eibb-ghmdzz?file=ExampleComponents.js
  2. click add item
  3. click add item

Expected Second iteme added to both non-virtualized and virtualized list

Actual virtualized list goes blank

Note: if you remove initialTopMostItemIndex entirely it works.

@chrisdostert thank you for the test case, resolved. I am about to release v1 over the weekend, so I will not publish a new beta for that.
