`ci skip` does not skip CI pipeline for MR on gitlab-org/gitlab

With #200037 (closed), [ci skip] in the commit message does not help me not trigger a CI pipeline for MR on gitlab-org/gitlab.

Example

• !26233 (merged)
  • https://gitlab.com/gitlab-org/gitlab/pipelines/122235132 is for Pipelines for Merged Results with a single commit with [ci skip]

Search words

• git push -o ci.skip cf. https://docs.gitlab.com/ee/user/project/push_options.html#push-options-for-gitlab-cicd
