Ansible group_vars environment variable subsitution

Put this in group_vars/all:

default_environment:
  HOME2: "{{ ansible_env.HOME }}"

When using in a task to define environment:

environment:
  "{{ default_environment }}"

I get this:

The field 'environment' has an invalid value, which includes an undefined variable. The error was: {u'HOME2': u'{{ ansible_env.HOME }}'}: 'ansible_env' is undefined
exception type: <class 'ansible.errors.AnsibleUndefinedVariable'>

Is there a way to define a group variable based on the current remote environment variables, $HOME in this case?

EDIT: Per request, reproducible case:

test.yml

- name: Test
  hosts: hosts1
  become: true
  become_user: user1

  environment:
    "{{ default_environment }}"

  tasks:
    - debug:
        msg: "{{ ansible_env }}"

group_vars/all

default_environment:
  HOME2: "{{ ansible_env.HOME }}"

Output when run with ansible-plyabook test.yml

PLAY [Test] ********************************************************************************************************************************************************************************************************************************


TASK [Gathering Facts] *********************************************************************************************************************************************************************************************************************

fatal: [host1]: FAILED! => {}

MSG:

The field 'environment' has an invalid value, which includes an undefined variable. The error was: {u'HOME2': u'{{ ansible_env.HOME }}'}: 'ansible_env' is undefined
exception type: <class 'ansible.errors.AnsibleUndefinedVariable'>
exception: {u'HOME2': u'{{ ansible_env.HOME }}'}: 'ansible_env' is undefined

        to retry, use: --limit @/work/ansible/test.retry

The error message is:

'ansible_env' is undefined

You did not gather the facts.

Run a play before the one you try to gather facts only, without declaring the environment:

- name: Test
  hosts: hosts1
  become: true
  become_user: user1

- name: Test
  hosts: hosts1
  become: true
  become_user: user1
  gather_facts: false

  environment:
    "{{ default_environment }}"

  tasks:
    - debug:
        msg: "{{ ansible_env }}"
