Environment on task level doesn't override play level definition when used with loops

[msoltyspl]

For example, the following yaml:

  environment:
    str: "play level"
  tasks:
    - name: test 1
      command: "/bin/echo $str"
      environment:
        str: "task level"
    - name: test 2
      command: "/bin/echo $str"
      with_items: [ 1, 2, 3]
      environment:
        str: "task level"

And execute: ansible-playbook bug.yml -v

Task 'test 1' will have 'task level' in stdout
Task 'test 2' will loop 3 times with 'play level' in stdout

IF environment is not defined on play-level, 'test 2' will use the task-level setting.
