Description

Parent of nested object array is the array of object itself and not the parent object

Steps to reproduce

Create collection

{
	"name": "vids",
	"fields": [
		{
			"name": "tags.id",
			"type": "string[]",
			"facet": true
		}
	],
	"enable_nested_fields": true
}

Import a document

  {
    "tags": [
      {
        "id": "tag-1",
        "name": "name of tag 1"
      },
      {
        "id": "tag-2",
        "name": "name of tag 2"
      }
    ]
  }

Search with facet

q: *
facet_by: tags.id
facet_return_parent:  tags.id 

http://127.0.0.1:8108/collections/vids/documents/search?q=*&facet_by=tags.id&facet_return_parent=tags.id

Result

    "facet_counts": [
        {
            "counts": [
                {
                    "count": 1,
                    "highlighted": "tag-2",
                    "parent": [
                        {
                            "id": "tag-1",
                            "name": "name of tag 1"
                        },
                        {
                            "id": "tag-2",
                            "name": "name of tag 2"
                        }
                    ],
                    "value": "tag-2"
                },
                {
                    "count": 1,
                    "highlighted": "tag-1",
                    "parent": [
                        {
                            "id": "tag-1",
                            "name": "name of tag 1"
                        },
                        {
                            "id": "tag-2",
                            "name": "name of tag 2"
                        }
                    ],
                    "value": "tag-1"
                }
            ],
            "field_name": "tags.id",
            "sampled": false,
            "stats": {
                "total_values": 2
            }
        }
    ],

Expected Behavior

Parent of tag-1 shoud be :

 {
    "id": "tag-1",
    "name": "name of tag 1"
 }

Parent of tag-2 shoud be :

 {
    "id": "tag-2",
    "name": "name of tag 2"
 }

Actual Behavior

Looks like the parent is the complete tags field, and not the tag object itself.
