The root you see isn't the plant's only root. It's likely one of many. Peeking out of the hole, likely the root tip it will wither-up and die, but this does not kill a plant. It doesn't even kill the entire root.

Do not transplant till the leaftips grow over the edge of the cup. In other words, if you look down at the plant from above, and can still see edges of the cup...hold off on transplanting.
