Describe the bug
Using VirtuosoMockContext to test components using Virtuoso fails as soon as initialTopMostItemIndex is set to something other than undefined or 0.

Reproduction

  1. Open this Sandbox: https://codesandbox.io/p/sandbox/heuristic-morning-87qd4l
  2. Run yarn test in a terminal.
  3. Note that tests are failing.
  4. Comment out the line involving initialTopMostItemIndex.
  5. Notice tests are passing.

Expected behavior
VirtuosoMockContext works even when initialTopMostItemIndex is set.

Additional context
react 18.2.0
react-virtuoso 4.6.2
