In the previous change we were able to re-use a pre-computed value in order to eliminate a bunch of SQL queries.
For multi-select cases, it's not possible to apply the same approach because 1 artifact might have more than 1 line (due to multiple values). Hence we have to re-query for multi-select values. However we should avoid to re-query each field independently or we will end with O(Nb rows x NB fields with multi-select values).
The solution is to pre-fetch the values before rendering to lower the number of queries to O(NB fields with multi-select values).
