Disconnect in a many-to-many relationship removes unrelated relations

Suppose my data model is such:

type User {
    id: ID! @unique
    email: String! @unique

    # a list of people the user follows
    follows: [User!]! @relation(name: "Follows")
    # a list of people following this user
    followers: [User!]! @relation(name: "Following")
}

So a user can follow other users and can have users follow them. Pretty simple. Our starting state for 3 users is:

Now, suppose my user (top one) follows the other two using the following code:

    async userFollow(loggedInUserId: string, userToFollowId: ID_Input, info?: GraphQLResolveInfo | string): Promise<User> {
        await this.db.mutation.updateUser({
            where: {id: loggedInUserId}, data: {
                follows: {
                    connect: [{id : userToFollowId}]
                }
            }
        }, "{ id }");

        return this.db.mutation.updateUser({
            where: {id: userToFollowId}, data: {
                followers: {
                    connect: [{id: loggedInUserId}]
                }
            }
        }, info);
    }

The result would be as you'd expect: screen shot 2018-08-20 at 14 31 00

Now, here is where it goes wrong. I unfollow user Jane using the following code:

    async userUnfollow(loggedInUserId: string, userToUnfollowId: ID_Input, info?: GraphQLResolveInfo | string): Promise<User> {
        await this.db.mutation.updateUser({
            where: {id: loggedInUserId}, data: {
                follows: {
                    disconnect: [{id : userToUnfollowId}]
                }
            }
        }, "{ id }");

        return this.db.mutation.updateUser({
            where: {id: userToUnfollowId}, data: {
                followers: {
                    disconnect: [{id: loggedInUserId}]
                }
            }
        }, info);
    }

And the output is: screen shot 2018-08-20 at 14 32 57

As you can see, unfollowing one user has resulted in the other user's followers connection to also be removed, while the follows connection of the user who initiated the action remains correct resulting in an invalid state.

Expected behavior I'd expect the followers connection of the unrelated user in this transaction (John) to be unchanged.

Additional information This bug looks like https://github.com/prisma/prisma/issues/2810 but I should be on a version of Prisma that's already fixed it.
