Overrides not working when calling xo with absolute paths

I have this in my package.json:

"xo": {
  "extends": "xo-react",
  "parser": "babel-eslint",
  "plugins": ["react"],
  "envs": ["node", "browser"],
  "rules": {
    "react/forbid-component-props": 0,
    "react/jsx-closing-bracket-location": ["error", "tag-aligned"]
  },
  "overrides": [{
    "files": "src/client/components/*.js",
    "rules": {
      "unicorn/filename-case": [
        "error", {"case": "pascalCase"}
      ]
    }
  }, {
    "files": "src/client/containers/*.js",
    "rules": {
      "unicorn/filename-case": [
        "error",
        {"case": "pascalCase"}
      ]
    }
  }]
}

And I have the file src/client/components/ExtendedReferenceManyField.js

Now, if I call

$ xo src/client/components/ExtendedReferenceManyField.js

it finishes without errors. However, calling:

$ xo /home/user/dev/project/src/client/components/ExtendedReferenceManyField.js

will output:

  src/client/components/ExtendedReferenceManyField.js:1:1
  ✖  1:1  Filename is not in kebab case. Rename it to extended-reference-many-field.js.  unicorn/filename-case

  1 error

I stumbled on this while using lint-staged in my project.

I believe I have fallen into the same issue when using lint-staged (http://npmjs.com/package/lint-staged) where it may be the case it sends absolute paths since my overrides config has no effect at all.

This Fails

{
  "lint-staged": {
    "*.js": [
      "xo --fix",
      "git add"
    ]
  },
  "xo": {
    "semicolon": false,
    "overrides": [
      {
        "files": "packages/shop-app/**",
        "envs": [
          "node",
          "browser"
        ]
      }
    ]
}

$ lint-staged
✔ Running tasks for package.json
❯ Running tasks for *.js
   ✖ xo --fix
     → ✖   24:4   postMessage is not defined.
     git add
✖ xo --fix found some errors. Please fix them and try committing again.

This Works

{
  "lint-staged": {
    "*.js": [
      "xo --fix",
      "git add"
    ]
  },
  "xo": {
    "semicolon": false,
    "overrides": [
      {
        "files": "/Users/zanona/Developer/my-app/packages/shop-app/**",
        "envs": [
          "node",
          "browser"
        ]
      }
    ]
}

$ lint-staged
