Wrong order using raw HTTP with pipelining

[raw-phil]

Nuclei version: v3.2.7

Current Behavior:

Nuclei send raw HTTP requests in wrong order when pipelining is active.

Expected Behavior:

Template:

id: multiple-raw-pipeline
info:
  name: Test Raw pipeline
  author: raw-phil
  severity: info

http:
  - raw:
      - |+
        GET / HTTP/1.1
        Host: {{Hostname}}

      - |+
        POST /testing HTTP/1.1
        Host: {{Hostname}}

    unsafe: true
    pipeline: true
    matchers:
      - type: word
        words:
          - "Test matcher"

I expect that nuclei will send first the GET and then the POST request, but the order is inverted.

$ nc -l 127.0.0.1 8080
POST /testing HTTP/1.1
Host: 127.0.0.1:8080

GET / HTTP/1.1
Host: 127.0.0.1:8080

Steps To Reproduce:

nuclei -t ./wrong-order-raw.yaml -u http://127.0.0.1:8080 --debug
