Hello Hackers!
Re. https://www.postgresql.org/message-id/CAFS4TJb-
7VTQQrnOi0g6MaoxMfEK9LzCds2yG%2BByS-mLHwydQA%40mail.gmail.com
We extracted the function bound to onSelectedRangesChanged from sqleditor!
- we read through the existing implementation and wrapped it in
`web/regression/javascript/selection/set_staged_rows_spec.js`
- we made some changes for clarity
Thanks,
Joao and George
