• Electron version: 1.7.9
• Operating system: macOS

Expected behavior

navigator.languages should return array of user's preferred languages, e.g. ["en-US", "zh-CN", "ja-JP"]

Actual behavior

navigator.languages returns an empty array []

How to reproduce

Create a primitive HTML file that logs navigator.languages into console. Then try loading via file://, http and inside Electron's renderer process. The first two will give you actual results while renderer yields empty array.
