No Autocomplete Inside webpack.config.js

[adityapurwa]

• VSCode Version: 1.19.3
• OS Version: Windows 10 Pro - 10.0.16299

Steps to Reproduce:

1. Open Visual Studio Code
2. Add webpack dependency ($ npm install --save-dev webpack).
3. Create webpack.config.js, see below.

module.exports = {
  // Ctrl+Space here, no autocomplete for possible webpack configuration entries.
}

Does this issue occur when all extensions are disabled?: Yes

I am sure that I used to be able to have auto complete inside webpack config files
