[BUG] NPM 10.6.0 outputs new lines when running npx

[broksonic21]

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

With NPM 10.5.2, logs are clear when running npx:

~/git/personal/test (main ✔) npx eslint

but with 10.6.0, there's new logging that shows up - this breaks tools looking for outputted strings in the results, as it's unexpected. I'm seeing this break some github actions expecting results from commands too: see wearerequired/lint-action#789

It's happening with any and all npx commands

~/git/personal/test (main ✔) npx eslint

> REDACTED@0.1.0 npx
> eslint

Expected Behavior

No unexpected logs being written out

Steps To Reproduce

Using npm 10.5.2
run any command with npx - don't get the logs

Using npm 10.6.0
run any command with npx - get the log lines

Environment

• npm: 10.6.0
• Node.js: 20.12.2
• OS Name: Mac
• System Model Name: MacBook Pro

Note: also seeing on Ubuntu on Github Actions

Looks like we missed a spot on banner suppression.

Thanks for testing the latest npm so quickly @broksonic21. npm@10.6.0 was a complete overhaul of the display layer. We thought we got everything but obviously missed this one.

Thanks for quick response/getting a fix in action. It broke our CI when renovatebot prompted me to update (see wearerequired/lint-action#789) so was nice and quick.

I made #7421 to fix this. This likely won't have to wait for our typical (bi-)weekly release cycle. I think we should put out a quick patch for this a few others.
