Filtering multivalue reference fields to contain multiple specified values does not work

Hi. in jsonapi website write for multivalue field i can call this url

GET /comments?filter[post]=1,2 HTTP/1.1

i expect bellow query return only articles that have term 508 AND 511 but seems this query all article that have 508 OR 511 term id:

http://backend/api/node/article?filter[and-group][group][conjunction]=AND
&filter[taxonomy_term--group][condition][path]=field_group.drupal_internal__tid&filter[taxonomy_term--group][condition][operator]=IN&filter[taxonomy_term--group][condition][value][]=508
&filter[taxonomy_term--group][condition][memberOf]=and-group&filter[group-b][condition][path]=field_group.drupal_internal__tid&filter[group-b][condition][operator]=IN&filter[group-b][condition][value][]=511
&filter[group-b][condition][memberOf]=and-group&include=field_group

how can i write a json query for that?
