url change after submitting

Hello !
After comment sending, the url change : …https://Mysite/PostName/#comment-27.
Do you know how to remove that, because if I refresh the page, I’ll move to this url.
I’ve try to put this php code in the function.php file:

add_filter('comment_post_redirect', 'redirect_after_comment');
 function redirect_after_comment($location)
  {
   return $_SERVER["HTTP_REFERER"];
  }

,but troubleshouting appear after submit (#respond are reapeat, etc).
Can I merge this code with your, or parameter that somewere?
thanks for your help
