* Computes the list of rows that are reachable by scroll.

* - If the pagination is disabled or in server mode, it equals all the visible rows.
* - If the row tree has several layers, it contains up to `state.pageSize` top level rows and all their descendants.
* - If the row tree is flat, it only contains up to `state.pageSize` rows.
