Job log adds new lines (a carriage return) after moving gitlab-runner to kubernetes helm chart

Summary

When job dynamically append text line, the job log adds a new line each time. It appeared after we moved gitlab-runner to kubernetes executor (helm deploy on gke)

What is the current bug behavior?

Currently it adds new lines at each sequence

What is the expected correct behavior?

No new lines appear

Relevant logs and/or screenshots
