parallel command processes are not killed when to kill walter process

[takyoshi]

I have a question about the behavior when a walter process is canceled.

I expected that when walter process is killed, parallel processes are killed. But theses processes were running after the walter process was killed. Is that behavior by design?

below my pipeline and results:

pipeline:
  - name: Start parallel pipelines
  - name: Env var checks
    type: command
    command: echo "hello, $USER_NAME"
    report_full_output: true
  - name: parallel start
    parallel:
    - name: long running 1
      type: command
      command: ./long_run.sh
      directory: /home/vagrant/scripts 
    - name: long running 2
      type: command
      command: ./long_run.sh
      directory: /home/vagrant/scripts 
    - name: long running 3
      type: command
      command: ./long_run.sh
      directory: /home/vagrant/scripts 
  - name: End parallel pipelines

operation and results:
