Why do you rewrite ref of TRIGGER_PAYLOAD?

GitLab CI/CD
,

I trigger my pipeline from Github etc.
https://gitlab.com/api/v4/projects/12345678/ref/main/trigger/pipeline?token=glptt-237c8123836c85b299ff6d99f3dd12827c23de94
with payload

{
  "ref": "refs/heads/test-branch",
  "before": "515817106e7b9ca89413499881c6a0846fe06ddd",
  "after": "03288450030a3d1db34c144c28b38f563adeff95",
  "repository": { ... }
  ...

But inside the Gitlab pipeline I see
cat $TRIGGER_PAYLOAD

{
  "ref":"main",
  "before":"515817106e7b9ca89413499881c6a0846fe06ddd",
  "after":"03288450030a3d1db34c144c28b38f563adeff95",
  "repository":{ ... }
  ...
}

Why do you rewrite initial payload and how can I see my initial ref?
Looks like a bug and you shouldn’t touch the data you receive externally.
