Right Joy-Con "ghosting" pressing buttons by itself

A little while ago my younger sister was playing with the Switch. My brother got mad at her for some reason and whacked the Switch out of her hands. The Switch landed right on the R button (the slim button on the right of the Joy-Con) and it cracked in half, rendering the button useless.

The system still continued to "work" for a little while, however eventually I noticed that the right joy con would start pressing random inputs. It would always be trying to go home and it would never work how I wanted it to work. I'm thinking maybe the logic board inside the Joy-Con was cracked. What do you guys think?
