Will a GFCI or AFCI circuit breaker trip if it only sees a return current on the neutral that is from another circuit due to crossed neutrals in a Jbox.

For example, the GFCI circuit feeds bathroom receptacles but does not have any load on it, however the neutral of this circuit has been crossed with a non protected circuit in the same junction box, with out any load on the GFCI will it trip if it sees a return current on the neutral that is from another circuit?

Thanks
