According to the Ran, what would be the halacha if the 2 pieces (salty and non-salty) were touching? Does anyone pasken like the Ran?

According to the Ran, if they are touching, both are prohibited, even if one piece is not salty. (According to him, the case where the salty piece doesn't absorb is limited to when the actual pieces are not in contact -- only the liquid.) The Rama in siman 105 says we should pasken like the Ran, unless there is loss (יש להקל במקום הפסד).
