[BUG] globally installed package from src does not include all files

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

in a fresh container
docker run --rm -t -i -v $(dirname $SSH_AUTH_SOCK):$(dirname $SSH_AUTH_SOCK) -e SSH_AUTH_SOCK=$SSH_AUTH_SOCK node:16 /bin/bash

given the package foo with package.json

{
  "name": "@user/foo",
  "version": "21.12.8-5f6d932",
  "bin": {
    "foo": "./bin/run"
  },
  "main": "lib/index.js",
  "types": "lib/index.d.ts",
  "engines": {
    "node": "16.13.1",
    "npm": "8.1.2"
  },
  "files": [
    "bin/",
    "lib/",
    "src/",
    "types/",
    "package-lock.json",
    "package.json",
    "README.md",
    "tsconfig.json"
  ],
  "scripts": {
    "postinstall": "npm run build",
    "build": "tsc"
  }
}

Installing the package in a custom dir npm i --ignore-scripts --prefix ./foo github:User/foo gives us the tree

README.md  bin	package.json  src  tsconfig.json  types

whereas npm i -g --ignore-scripts github:User/foo gives us

src

It looks like files field in package.json is not used while installing package from source globaly

same behaviour in our CI (github actions)

Expected Behavior

installing package from source globaly should behave the same way as locally

Steps To Reproduce

No response

Environment

• npm: 8.2
• Node: 16.13.1
• OS: ubuntu 20.04
• platform:
• npm config:

; node bin location = /usr/local/bin/node
; cwd = /root/.npm/_cacache/tmp/git-clonepBND4z
; HOME = /root
; Run `npm config ls -l` to show all defaults.

Reproduce the difference between npm i --ignore-scripts --prefix ./foo github:User/foo and npm i -g --ignore-scripts github:User/foo using the provided package.json and files list. Compare the resulting package trees, then trace npm CLI handling of globally installed GitHub source packages and the files field. Done means both installation modes include the same expected files.
