[#12946] - Filtering on report does not work for groups when there are sort fields defined

I have attached a test report made on a CSV data adapter.

Steps to reproduce:
1. define a group in the report
2. drag some fields to be printed in the group (tried both with header or footer)
3. define a sort field in the report
4. define a filterExpression which should result in no data being printed (in my case, I filtered for the field $F{name} when it's equal to a string that is not found in the csv file - $F{name}.equals("no_existing_name"))
5. set when no data - All sections no detail

Expected output should be an enpty page, which does not contain any record, since there's no record where the field $F{name} has the value "no_existing_name".
But the output provides one record.

I believe it has a similar behavior for queries.
