> *Steps:*
>  # From Web UI, run the following query:
> {noformat}
> select * 
> from (
>     select employee_id, full_name, first_name, last_name, position_id, position_title, store_id, department_id, birth_date, hire_date, salary, supervisor_id, education_level, marital_status, gender, management_role 
>     from cp.`employee.json` 
>     union
>     select employee_id, full_name, first_name, last_name, position_id, position_title, store_id, department_id, birth_date, hire_date, salary, supervisor_id, education_level, marital_status, gender, management_role 
>     from cp.`employee.json` 
>     union
>     select employee_id, full_name, first_name, last_name, position_id, position_title, store_id, department_id, birth_date, hire_date, salary, supervisor_id, education_level, marital_status, gender, management_role
>     from cp.`employee.json`)
> where last_name = 'Blumberg'
> {noformat}
>  # While query is running, try open the Profiles page (or any other). If It completes too fast, add some unions to the query above.
> *Expected result:*
>  Profiles page should be opened. The running query should be listed.
> *Actual result:*
>  The Web UI hangs until the query completes.
> *Notes:*
> - If you open another tab with Web Console, it also stuck when the query is running.
> - If the query is started from sqlline, everything is fine.
