Rotor still rotating when angular velocity 0

v2.2.0.2116

This issue just started happening after 4 hours 3 minutes of gameplay, while my Boring Miner ship was docked with the MMS Mammoth. When I complete mining, I turn off the drills and set the rotor's angular velocity to 0 to prevent it from moving while docked or in transit during flight.

After docking while in external view, I noticed that the rotor was still spinning at a very slow velocity. To make sure it was not visual issue with the external view, I switched to the cockpit view, and the rotor was still spinning. I check for an input error, I went in and re-entered 0 into angular velocity to make sure it was actually 0. The rotor remained spinning. I then tried spinning the rotor using the mouse, both left and right, and on stopping, the rotor resumed its slow spinning.

My current guess is that this is some sort of creeping small number issue due to the long term of play. (0 isn't exactly 0, but some off number like 0.001 or 0.005) that isn't showing in the input field when I Ctrl+Click on it.

I also tried changing the number from 0 to 0.5 then back to 0, but it is still spinning to the right (angular velocity negative by some non-0 amount.

See attached video. You can see the rotor spinning behind the input window.

Exiting and reloading the current game session slowed the rotor down but did not completely stop the rotation to the right. It is barely noticeable after the reload.

Completely exiting the game and launching the game again, then going back into the saved game seems to have drastically slowed the rotation of the rotor.

I was expecting a 0 angular velocity would have completely stopped the rotor while the ship is powered.

On a side note the MMS Mammoth does have the large gravity generator installed and operational. But I would have expected that to be like planetary gravity, and the rotors would not spin unless I set angular velocity to a non-zero value.

FYI I can tell it is still rotating due to the heavy armor rivet dots that are slowly appearing along the straight edge of the curved conveyor outside the front of the cockpit.
