Slow costmap update

[tomy983]

Description In 3D and 3D beta panels, while visualizing move_base costmap 2D /move_base/local_costmap/costmap the uptades are very slow (0.02Hz). This is probably because Studio does not also subscribe to /move_base/local_costmap/costmap_updates. Confronting Studio with RVIZ, in both adding the costmap to the scene is very similar, but rviz (without notice) also subscribe to the /move_base/local_costmap/costmap_updates topic and most certainly uses also this topic to update the costmap on the screen as i can see using rosnode info move_base

• Version: 1.18.0
• OS: windows
• ROS distro (if applicable): noetic

Steps To Reproduce add costmap to the 3d scene in rviz and studio.

Current Experience In Rviz the map updates are loaded into the costmap view. In studio the costmap is not updated unless a new map is received.

Desired Experience The costmap in the 3D panel should take in considarition the updates coming from /move_base/local_costmap/costmap_updates of type map_msgs/OccupancyGridUpdate (same thing for global costmap..)
