I guess it is strongly discouraged to have sleep in EDT to ensure UI does not become unresponsive.
Also, it's not the same test but same bugid was being erroneously used in two different tests as both are failing in macos ARM..The other test is decoupled from this and will be investigated as per different bugid..Current PR for this test stands as it is..
