[webkit-dev] Looking forward to get an advice about event listeners for navigator.battery.

There's likely a better design for your patch.  For example, each
BatterManager could register itself with the BatteryController.  When
one of these events occurs, the BatteryController could fire the event
on all the BatterManager class, regardless of whether they have
listeners added.  That would relieve you of the need to override any
of EventTarget's methods (and reduce the amount of state that
BatteryController could need to keep).
