Missing [path] in module.less files [webpack 4]

*my.module.less* in chrome devtools
Before webpack 4.1.1
```
var escape = require("../../../node_modules/css-loader/lib/url/escape.js");
exports = module.exports = require("../../../node_modules/css-loader/lib/css-base.js")(true);
// imports

// module
exports.push([module.id, ".app-controllers-___header-module__header___...snip

// exports
exports.locals = {
"header": "app-controllers-___header-module__header___2cDAd",
"link": "app-controllers-___header-module__link___9ZF3f",
"title": "app-controllers-___header-module__title___3zdsk",
"versionName": "app-controllers-___header-module__versionName___P3mUm",
"loggedInUser": "app-controllers-___header-module__loggedInUser___2g4NC",
"settingsAndInfo": "app-controllers-___header-module__settingsAndInfo___3tMjw",
"usernameLabel": "app-controllers-___header-module__usernameLabel___12VlL",
"userOptionsList": "app-controllers-___header-module__userOptionsList___392Md",
"userOptionsListItem": "app-controllers-___header-module__userOptionsListItem___1axLL",
"readonlyLabel": "app-controllers-___header-module__readonlyLabel___3TM1g",
"outdatedStyle": "app-controllers-___header-module__outdatedStyle___1Hj_P",
"outdatedLink": "app-controllers-___header-module__outdatedLink___3w-ME"
};
```

After webpack 4.1.1:
```
var escape = require("../../../node_modules/css-loader/lib/url/escape.js");
exports = module.exports = require("../../../node_modules/css-loader/lib/css-base.js")(true);
// imports

// module
exports.push([module.id, ".___header-module__header_...snip
// exports
exports.locals = {
"header": "___header-module__header___2hFEv",
"link": "___header-module__link___3788-",
"title": "___header-module__title___1ltkk",
"versionName": "___header-module__versionName___PiO_N",
"loggedInUser": "___header-module__loggedInUser___3rJB5",
"settingsAndInfo": "___header-module__settingsAndInfo___3En63",
"usernameLabel": "___header-module__usernameLabel___2IGNx",
"userOptionsList": "___header-module__userOptionsList___NyxVd",
"userOptionsListItem": "___header-module__userOptionsListItem___3U7ZZ",
"readonlyLabel": "___header-module__readonlyLabel___1XVj-",
"outdatedStyle": "___header-module__outdatedStyle___2aBI2",
"outdatedLink": "___header-module__outdatedLink___3RjtB"
};
```

My rule:
```
{
test: /\.module\.less$/,
use: [
{
loader: "style-loader",
options: { sourceMap: true }
},
{
loader: "css-loader",
options: {
sourceMap: true,
modules: true,
importLoaders: 1,
localIdentName: "[path]___[name]__[local]___[hash:base64:5]"
}
},
{
loader: "postcss-loader",
options: {
sourceMap: true,
plugins: loader => [
require("postcss-import")({
root: loader.resourcePath
}),
require("postcss-cssnext")({
warnForDuplicates: false
}),
require("postcss-csso")({
zindex: false
})
]
}
// publicPath: ""
},
{
loader: "less-loader",
options: { sourceMap: true }
}
]
};
```

I'm guessing here that `[path]` is the item missing in the output.
Any thoughts? Is this a bug?

Riproduci l’output di webpack 4.1.1 per my.module.less usando la configurazione mostrata di style-loader, css-loader, postcss-loader e less-loader. Confronta l’output del modulo generato e la gestione di localIdentName con l’output precedente; il lavoro è completato quando si determina se [path] viene omesso dalla catena di loader e si aggiunge o si identifica un test di regressione se il comportamento è un bug.
