The swapping mechanism produces different results depending on of there are ratsnets

Place a trimmer potentiometer in the breadboard:

Swap to a rotary potentiometer:

The swapping mechanism adds a wire for each of the connectors of the potentiometer, ok.

Now, add another pot to the breadboard as before. Go to the sch view and add a resistor. Connect the resistor to the wiper of the potentiometer.

Change to the breadboard view and move the resistor with a ratsnet from the resistor to the potentiometer

Swap to the rotary potentiometer

Notice that the wiper does not have a cable joining the connector with the breadboard.

Expected Behaviour

The wire is placed to make the behavior homogeneous.

And also noticed that the wire that connects the resistor with the pot in the schematic view disappears
