[BUG] npm spinner during npm config edit causes editing issues #9142

Is there an existing issue for this?

• I have searched the existing issues

This issue exists in the latest npm version

• I am using the latest npm

Current Behavior

I am using nvm v11.12.0 with nodejs 24 on Fedora Linux.

When I run npm config edit to attempt to edit my config, npm displays a spinner and it appears above vim when attempting to edit the config:

When scrolling down through the config file, the spinner leaves a path of destruction in its wake by erasing lines and leaving spinner frames along the left-hand edge of the editor:

Expected Behavior

There should not be a spinner present when the editor opens for configuration changes.

Steps To Reproduce

1. On Fedora Linux using npm v11.12.0 running under NodeJS with nvm...
2. With system editor configured as vim
3. Run npm config edit
4. See error...
