bug-report

### Describe the bug I am trying to simulate a fast rotating vehicle, but the… gyro data seems to get inverted at high rotating rates (~50rad/s). ### To Reproduce Use this branch: https://github.com/PX4/PX4-Autopilot/tree/pr-monocopter ``` make px4_sitl gazebo-classic_monocopter ``` ![349954900-a4437eaf-4b76-4d7c-a0ac-eae7eb8b9580](https://github.com/user-attachments/assets/9e50cef0-6c59-4c43-ba48-04637f4cb637) ### Expected behavior In case the gyro saturates, it should report clipping rather than report some other random value ### Screenshot / Media ![image](https://github.com/user-attachments/assets/78843a22-f19b-4e3b-b4a2-3a3b2466114a) ### Flight Log https://review.px4.io/plot_app?log=faa25343-059d-4a67-96ca-101816085007 ### Software Version https://github.com/PX4/PX4-Autopilot/tree/pr-monocopter ### Flight controller SITL ### Vehicle type None ### How are the different components wired up (including port information) _No response_ ### Additional context _No response_
