Short description of error
Walk navigation can rotate the camera with locked Rotation values. I consider it as a bug cause I can't move the camera in walk nav with Location locked and it shouldn't rotate by design IMO.
Exact steps for others to reproduce the error
Create a camera, lock rotation in Transform tab, enter camera via ctrl+0 and use walk navigation to rotate it.
