without knowing the insides at all - my layman guess is that the rotation sensor somehow stuck? I'm not sure if this is even possible form a technical point of view?

Thanks for reporting your experiences. I do not remember anyone posting in this forum, or the other forums I like, about a failure in the rotation sensor. So this is a first!

I might be mistaken but the sensor could be a small device with a little ball inside, and when you rotate the camera the ball shorts out different contacts. There would be at least 5 separate contacts in this sensor. One of them is a little bit dirty!

This is a low cost one axis version, but has a very good explanation. A camera might use four of these, or it might use an integrated optical detector such as this one:

RPI-1035 : Optical Sensors (rohm.com)

These use power though, so might not be that great.

I don't think this can be fixed unless you replace the entire sensor, so your workaround is the best solution.
