Subject: [PATCH] fix: total row count for selection went up when grouping

Beforehand the total row count went up when grouping.

This is fixed by using the core row modal as none transformation has happend. From my understanding this will always give the amount of possible rows to select as this is the max amount of rows given to the table.
