stop-at-first-match with headless/fuzzing not working

[bizibabe]

Hello,

I don't understand why stop-at-first-match doesn't work in this template:

echo "https://www.bing.com/?test=1" | nuclei -dast -t test.yaml -headless

id: test-headless-match

info:
  name: test headless match
  author: Bizi
  severity: low
  
headless:
  - steps:
      - action: navigate
        args:
          url: "{{BaseURL}}"
      - action: waitload
    payloads:
      test:
        - "1"
        - "2"
        - "3"
    
    stop-at-first-match: true
    
    fuzzing:
      - part: query
        type: replace
        mode: single
        fuzz:
        - "{{test}}"
 
    matchers:
      - type: word
        name: bing
        words:
          - "www.bing.com"
        part: body

Is this normal?
Thank you,
Bizi
