Passing an environment variable to another job is not working with `artifacts:access: 'none'`

Summary

We have a pipeline that passes an environment variable (and a file artifact) from job 1 to job 2. Therefore, we use artifacts:reports:dotenv in job 1 as described in the docs.

While this config worked perfectly in the last weeks, the environment variable in job 2 is now empty.

Steps to reproduce

stages:
  - check

job-1:
  stage: .pre
  script:
    - echo "BUILD_VARIABLE=path/to/secret/config" > tf.env
  artifacts:
    access: 'none'  # We don't want users to download the config file
    paths:
      - path/to/secret/config
    reports:
      dotenv: tf.env

job-2:
  stage: check
  script:
    - echo "$BUILD_VARIABLE"     # This is empty!
    - cat path/to/secret/config  # This file exists (as expected)

We noticed that if we remove access: 'none' it works as expected. However, denying access to this artifact is mandatory for us and it worked previously.

Example Project

What is the current bug behavior?

The environment variable BUILD_VARIABLE is empty in job-2.

What is the expected correct behavior?

The environment variable BUILD_VARIABLE has the value path/to/secret/config in job-2.
