*
* The `navigator.getBattery()` reports the state of the battery and can be
* misused to fingerprint users for a short term. The API was removed from
* Firefox, but is still supported in browsers derived from Chromium.
* The wrapper mimics Firefox behaviour.
*
* \see <https://lukaszolejnik.com/battery>
*
* \bug Because we mimic Firefox behaviour, a Chromium derived browser
* becomes more easily fingerprintable. This can be fixed by properly
* wrapping `BatteryManager.prototype` getters and setters.
