Auto Accept Friend Requests BuddyPress

Question

I'm attempting to create a function that auto accepts friend request in Buddy Press, the function is as follows;

function bp_auto_accept_friend_request( $friendship_id, $friendship_initiator_id, $friendship_friend_id ) {

    friends_add_friend( 
        $friendship_initiator_id, 
        $friendship_friend_id, 
        $force_accept = true 
    );

    friends_accept_friendship( $friendship_id );
}

add_action('friends_friendship_requested', 'bp_auto_accept_friend_request', 200, 3);

The above function works by creating an entry in the wp_bp_friends table with a value of 1 for the is_confirmed column, however the default friendship request action is still being executed which adds an additional entry to the table saying unconfirmed.

id  initiator_user_id   friend_user_id  is_confirmed    is_limited  
2          1                   3             1              0   
3          1                   3             0              0   

So we have both a confirmed and unconfirmed entry for the same friendship. This means that on the user profile page it will appear as if you have both a confirmed friend and have a friend request from the same person.

The above function was adapted for simplicity from;

There's also this accepted answer from WPSE here;

How to auto-accept a friend-request in buddypress based on user meta

...which when adapted to my use case produced the same results described.

Any thoughts on how to prevent the default action? So far I can't unhook the request...
