[BUG] For a simple 4x4 map, the rviz plugin only shows a 3x3 grid #338

Map1.txt

With the map file above, and running the following command: rostopic pub -r 1 /gridmap grid_map_msgs/GridMap -f data/grid_map_msgs/GridMap/Map1.txt

Shows a reduced map in the GridMap rviz plugin: rviz_screenshot_2022_02_10-09_56_01

Not sure if this is just me doing something wrong, if it's a problem only in the plugin, or if it's a problem in the ROS conversion?
