Power and Free conveyor ignores stopped motor

Similar to this issue (which has since been fixed), if a Power and Free conveyor is stopped through a connected motor before the dogs are initialized, the conveyor will ignore this stop when items enter it.

To get the conveyor to stop, the motor has to change from being active to a stop again.

Update: This is incorrect - was mistake in testing.

@Felix Möhlmann I've found that by instead setting the speedRatio of the motor to zero you can avoid this issue with stopping before items have entered.

Doesn't seem to work for me. Have you done anything differently? (Tested in 24.0.2)

I used this in the code snippet:

Model.find("Motor1").as(Conveyor.Motor).speedRatio=0;
