Hidden needs are incorrectly assigned a parent_need link

[PierreEtienneJ]

Description

When two needs directive follow each other and the second have option :hide:, a parent_need link is incorrectly assigned to the previous directive when a :hide: option is used.

Steps to Reproduce

In rst file

.. req:: req-1

    requirement 1

.. req:: req-2

    requirement 2

text between 2 and 3

.. req:: req-3

    requirement 3

.. req:: req-a
    :hide:

    requirement A

.. req:: req-b
    :hide:

    requirement B

.. spec:: spec-c
    :hide:

    spec C

text between C and D

.. req:: req-d
    :hide:

    requirement D


.. needtable::
   :columns: id;title;parent_needs

Explanation

• req-1 and req-2 follow directly.
• req-2 and req-3 have a text between nodes
• req-3 and req-a follow directly and req-a have option hide
• req-a and req-b follow directly both have option hide
• req-b and spec-c follow directly both have option hide
• spec-c and req-d have a text between nodes and both have option hide

In needtable it's expected:

id	title	parent_needs
R_A7BB1	req-1
R_F1A88	req-2
R_C2CE3	req-3
R_8CA9D	req-a
R_3C018	req-b
S_13219	spec-c
R_490A1	req-d

But we have

id	title	parent_needs
R_A7BB1	req-1
R_F1A88	req-2
R_C2CE3	req-3
R_8CA9D	req-a	R_C2CE3
R_3C018	req-b	R_8CA9D
S_13219	spec-c	R_3C018
R_490A1	req-d

With needservice

from sphinx_needs.services.base import BaseService

extensions = [
    "sphinx_needs",
]

class MyService(BaseService):
    options = []
    def __init__(self, app, name, config, **kwargs):
        self.app = app
        self.name = name

        self.config = config
        super(BaseService, self).__init__()

    def request(self, options):
        nodes = [
            {
                "title": "req-1",
                "hide": False,
                "type": "req",
            },
            {
                "title": "req-2",
                "hide": False,
                "type": "req",
            },
            {
                "title": "req-3",
                "hide": True,
                "type": "req",
            },
            {
                "title": "spec-4",
                "hide": True,
                "type": "spec",
            }
        ]
        return nodes


needs_services = {
    'my-service': {
        'class': MyService,
        'class_init': {
        },
    },
}

in the rst

.. needservice:: my-service

.. needtable::
   :columns: id;title;parent_needs

Explanation:

• req-1 and req-2 are not hide.
• req-3 and spec-4 are hide

Expected:

id	title	parent_needs
R_A7BB1	req-1
R_F1A88	req-2
R_C2CE3	req-3
S_3811D	spec-4

But I have:

id	title	parent_needs
R_A7BB1	req-1
R_F1A88	req-2
R_C2CE3	req-3	R_F1A88
S_3811D	spec-4	R_C2CE3

Environment
