Steps to Reproduce

Give n the file

shell> cat testvars.yml 
---
test: "{{ foo }}"
foo: bar

the block below

    - block:
        - ansible.builtin.include_vars:
            file: testvars.yml
        - debug:
            var: test

gives

  test: bar

But, when the result is registered

    - block:
        - ansible.builtin.include_vars:
            file: testvars.yml
          register: result
        - debug:
            var: test

the variable won't be expanded

  test: '{{ foo }}'

Expected Results

The registered variable should not break the expansion of the included variables.
