The Sortable concern has a default scope that adds ORDER BY to all
queries. EXPLAIN ANALYZE shows that this additional ORDER BY statement
causes the SQL optimizer to use the wrong index, which leads to a load
time of 2.9 s vs 0.073 ms just for the SELECT call. The minimal
change here is to re-implement find_by using where and reorder to
remove the ORDER BY clause in IssuesController#index.

Closes #23075
