Orientation of `EgocentricCameraActor` flipped

I was running the example `sb3_move_boxes.py` and was looking at the observations returned from the actor and they seem to be flipped to the orientation that I expect them to be? Like the blue floor is at the top of the image and the gray sky at the bottom. Is this how it is supposed to be?

This is the observation from the CameraSensor. You can find a file with the environment I used [here](https://pastebin.com/L6NTpGGH).
