Disable Jetpack_Sync_Module_Posts action

How does one disable the Jetpack_Sync_Module_Posts class from hooking into the transition_post_status action?

Previously one could search for the add-on name and disable it but that seems to have changed from v12.4 to v12.7.

Here is the code I used previously:

    global $wp_filter;
    $hook = 'transition_post_status';
    $filters = $wp_filter[ $hook ];
    if ( is_object( $filters ) )
        $filters = $filters->callbacks;
    else
        return;

    foreach( $filters as $priority => $callbacks )
    {
        foreach( $callbacks as $callback )
        {
            // We're looking for a class.
            $function = $callback[ 'function' ];
            if ( ! is_array( $function ) )
                continue;
            $callback_class = $function[ 0 ];
            if ( ! is_object( $callback_class ) )
                continue;
            // We are looking for Jetpack.
            if ( get_class( $callback_class ) != 'Jetpack_Sync_Module_Posts' )
                continue;
            $function_name = $function[ 1 ];
            // And this specific function.
            if ( $function_name != 'save_published' )
                continue;

            // Found it. Remove it.
            $this->debug( 'Removing transition_post_status action for the post sync module.' );
            remove_action( $hook, $callback[ 'function' ], $priority, $callback[ 'accepted_args' ] );
        }
    }
