 I did few more tests and if I set it like below it works.

 {{{#!php
 <?php
 add_filter( 'wp_dropdown_users_args', array( $this,
 'display_additional_author_roles' ), 99, 2 );
 public function display_additional_author_roles( $query_args, $parsed_args
 ) {
                 if ( 'company' !== get_post_type() ) {
                         return $query_args;
                 }

                 $query_args['capability__in'] = array( 'administrator',
 'company_owner' );

                 unset( $query_args['capability'] );

                 return $query_args;
         }
 }}}

 Works with `role__in` too as long as I unset the `capability` key.
 The capability is set to `edit_posts` by default for CPT.

 When registering the CPT, the Authors support (metabox) in the CPT add /
 edit screen is not showing when I try to add:
 {{{#!php
 <?php
 'capability_type'    => array( 'company', 'companies' ),
 'map_meta_cap'       => true,
 }}}


 The other way I can set it as follows:

 {{{#!php
 <?php
 public function display_additional_author_roles( $query_args, $parsed_args
 ) {
                 if ( 'company' !== get_post_type() ) {
                         return $query_args;
                 }

                 $query_args['capability'] = 'publish_companies';

                 return $query_args;
         }
 }}}

 So every role that has the publish_companies capability will be listed as
 author.
 I am pretty sure this is the right way to go for it, but kinda confusing
 if we use the `capability__in` key.
