undefinedvalues for therowCountwhile fetching childrenhttps://github.com/mui/mui-x/blob/v7.x/packages/x-data-grid-pro/src/hooks/features/dataSource/useGridDataSource.ts#L185
v8 sets it to -1
I think that we can remove this altogether as it does not make sense to update root row count while updating children.
If you do, you don't have a mean to update the data via the same response, so your count cannot be correct.
