Cloned repeater

I see a lot of forum posts about clone fields inside repeaters, but I haven’t found any help with getting values from a clone of a repeater. For example, get_sub_field( 'sub_field_name' ) works on the original field, of course, but does not work on the cloned field. ACF treats the cloned field as a sub field of the clone, so get_sub_field( 'repeater_name' ) produces an array of the actual rows I want to process. It’s like I need to do while( have_rows() ) : the_row() inside my main while(have_rows) loop if the field is a clone of a repeater.

// $area = slug of the field
while( have_rows( $area, $page_id ) ) : the_row();
    $row = get_row();
    var_dump( $row );
endwhile;

Repeater field output:

array(2) {
  ["field_5a1d86e968289"]=>
  string(10) "search-bar"
  ["field_5a1d95b3d4cc2"]=>
  NULL
}

Clone field output: (single row includes multiple rows)

array(1) {
  ["field_5a1d8827cd34c_field_5a1d7ec7fba73"]=>
  array(2) {
    [0]=>
    array(2) {
      ["field_5a1d86e968289"]=>
      string(14) "featured-books"
      ["field_5a1d95b3d4cc2"]=>
      NULL
    }
    [1]=>
    array(2) {
      ["field_5a1d86e968289"]=>
      string(14) "featured-posts"
      ["field_5a1d95b3d4cc2"]=>
      NULL
    }
  }
}

Can I make have_posts() loop over the cloned fields, so they act as normal rows after the_row()?

This is the code I ended up with to handle the cloned repeater:

function my_acf_sections( $area = '' ) {
    if( ! function_exists( 'get_field' ) ) return;
    $page_id = get_queried_object_id();
    if( have_rows( $area, $page_id ) ) :
        while( have_rows( $area, $page_id ) ) : the_row();
            $section_content = get_sub_field( 'section_content' );
            if( $section_content ) {
                // Do stuff with fields
            } else {
                // Handle cloned repeater
                $clone = get_field_object( $area );
                if( ! isset( $clone['sub_fields'] ) ) continue;
                $clone = get_field_object( $area )['sub_fields'][0];
                if( $clone['_clone'] ) my_acf_sections( $clone['name'] );
            }
        endwhile;
    endif;
}

I’m open to suggestions for something better.
