In the demo there is a single resource with height over 18000 and client expects header to be repeated on every page.

We need to take such case into consideration:

1. Row should be exported correctly when it has massive height
2. Only events in the viewport should be rendered (ideally, they don't obstruct however they are not needed)
3. Events should be positioned correctly on every page (we got rid of translating the row, but for such cases it may be needed)
4. Make sure layoutFn works correctly with export
