MAVSDK-Python Telemetry set frequency (Hz) of attitude updates

I was working on some scripts for subscribing telemetry data and I had an issue with the function set_rate_attitude() which should handle the frequency of the attitude updates (attitude_quaternion, attitude_euler, attituda_angular_velocity_body). I tried to set frequency of some other telemetry topics and they worked, but for these three functions (attitude_quaternion, attitude_euler, attituda_angular_velocity_body) the set_rate_attitude functiion have’nt worked and I had to handle these with asyncio.sleep() command.

So I am curious whether I am the only one who faced this problem or it is some sort of bug.
