Figured a workaround for the above issue. We won't face infinite looping, if we perform the modify op after disabling table i.e. it works fine if we perform offline schema change for a table having region replica. Wondering whether it is an expected behaviour?

> *Steps to reproduce*
>  # Create a table with region replication set to a value greater than 1
>  # Modify any of the table properties, say max file size
> *Expected Result*
>  The modify table should succeed and run to completion.
> *Actual Result*
>  The modify table keep running infinitely
> *Analysis/Issue*
>  The problem occurs due to inifinitely looping between states {{REOPEN_TABLE_REGIONS_REOPEN_REGIONS}} and {{REOPEN_TABLE_REGIONS_CONFIRM_REOPENED}} of {{ReopenTableRegionsProcedure}}, called as part of {{ModifyTableProcedure}}.
> *Consequences*
>  For a table having region replicas:
>  - Any modify table operation fails to complete
>  - Also, enable table replication fails to complete as it is unable to change the replication scope of the table in source cluster
