Unable to create <NAME>.gitlab-ci.yml (or edit) using Edit UI button
Summary
Unable to create/edit filename with pattern <NAME>.gitlab-ci.yml that we're using on repo where we store our custom gitlab-ci shared template
Seems to be similar to #34443 (closed)
Steps to reproduce
Can be reproduce on gitlab.com or on-premise instance (>= 12.3)
Edit
if you try to edit <NAME>.gitlab-ci.yml it using Edit UI button
The file will be forcely renamed .gitlab-ci.yml
Create
Is not possible to create file <NAME>.gitlab-ci.yml using Edit UI button because is automatically renamed .gitlab-ci.yml
Example Project
https://gitlab.com/kakawait/gitlab-ci-edit-bug
Or any gitlab.com projects
What is the current bug behavior?
Automatic / force renamed <NAME>.gitlab-ci.yml to .gitlab-ci.yml (if I think pattern <NAME>.gitlab-ci.yml could be anything else is more about file extension *.gitlab-ci.yml)
What is the expected correct behavior?
Do not rename filenames...
Output of checks
This bug happens on GitLab.com
Workarounds
- Do not use UI
- Use Web IDE (not affected)
