[BUG] npm pack --json returns incorrect filename for scoped package

[pleunv]

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

When dealing with a scoped package, the file created on disk is of the format scope-package-1.0.0.tgz.
The filename that is reported by npm pack --json is incorrect as it's reported as @scope/package-1.0.0.tgz instead.
The filename reported by npm pack (without --json) is correct.

Expected Behavior

When running npm pack --json the reported filename property should be scope-package-1.0.0.tgz instead of @scope/package-1.0.0.tgz.

Steps To Reproduce

Given a package.json with the following:

{
  "name": "@scope/package",
  "version": "1.0.0",
}

The output of npm pack is the following, which includes the correct filename:

npm notice
npm notice 📦  @scope/package@1.0.0
npm notice === Tarball Contents ===
npm notice 0B  index.js
npm notice 53B package.json
npm notice === Tarball Details ===
npm notice name:          @scope/package
npm notice version:       1.0.0
npm notice filename:      @scope/package-1.0.0.tgz
npm notice package size:  167 B
npm notice unpacked size: 53 B
npm notice shasum:        ad1ef62b3d84c83033c896f0aee03b701c75b1e8
npm notice integrity:     sha512-NNdAGvap0FZo6[...]oW6ok5Rejsmag==
npm notice total files:   2
npm notice
scope-package-1.0.0.tgz

The output of npm pack --json is the following, which includes an incorrect filename property:

[
  {
    "id": "@scope/package@1.0.0",
    "name": "@scope/package",
    "version": "1.0.0",
    "size": 167,

    "filename": "@scope/package-1.0.0.tgz",
    "files": [
      {
        "path": "index.js",
        "size": 0,
        "mode": 420
      },
      {
        "path": "package.json",
        "size": 53,
        "mode": 420
      }
    ],
    "entryCount": 2,
    "bundled": []
  }
]
