Shorting pins via metal surface

One of my grid modules sits right next to a synth with metal case.

Both surfaces are in parallel, and the module’s magnets make it cling to the synth, shorting the pins.

Do I have to worry about malfunctions, or is this cared for in the electronics, disabling shorted circuits?

My best idea would be to cover the module’s side with tape, maybe with a piece of tissue on the contacts to not cover them in adhesive.
