Strange behavior of the carla spectator

[gunki-geek]

I implemented this simple code to test the spectator. However the spectator view is not aligned with the vehicle view. The car is looking forward while the spectator is looking backward.
`import carla
import math
import time

client = carla.Client('localhost', 2000)
client.set_timeout(10.0)
world = client.get_world()

blueprint_library = world.get_blueprint_library()
vehicle_bp = blueprint_library.filter('vehicle')[0]
spawn_point = world.get_map().get_spawn_points()[0]
vehicle = world.spawn_actor(vehicle_bp, spawn_point)

car_transform = vehicle.get_transform()

spectator = world.get_spectator()
while(True):
spectator.set_transform(car_transform)`

I am using carla 0.9.16
