Hi,

When I wrote the getBattery() prose, I made it so that getBattery()
would return a new promise every time it is called but it would always
return the same BatteryManager when the promise is resolved.

I realised that this requirement probably doesn't make much sense and we
might want to spec getBattery() as returning always the same promise. In
other words, navigator.getBattery() === navigator.getBattery(). The
intent isn't really to get the equality but that way, we simplify the
implementation because implementing this only require to keep track of
that one promise.

WDYT?
