If you check the QoS profile for sensor_data you will see that reliability is set to the best effort: https://github.com/ros2/rclcpp/blob/f160a8bc1d2b4f9a9fb0bba23d0b5d0f8c1afaab/rclcpp/include/rclcpp/qos.hpp#L168

Now, if you add a new visualization to RViz2 it will have reliability policy set to Reliable by default:

Therefore, just change reliability to Best Effort:

If you want to test, you can set --qos-profile to ros2 topic pub as:

ros2 topic pub --qos-profile=sensor_data /topic sensor_msgs/Range '{ range: 1, header: { frame_id: base_link } }'
