Masked variables still visible in the job log for any member role

In GitLab 12.2.0-ee GitLab Shell 9.3.0 GitLab Workhorse v8.8.0 GitLab API v4 Ruby 2.6.3p62 Rails 5.2.3

Using gitlab runner 12.2.0

job config:

test:
  stage: test
  script: 
    - echo ${test1}

masked evironment variables are still visible in the job build log: $ echo ${test1} 12345678

It is visible even for Reporter roles. How to hide masked vars from that view?
