* Summary of `ReactEventEmitter` event handling:
*
* - Top-level delegation is used to trap native browser events. We normalize
* and de-duplicate events to account for browser quirks.
*
* - Forward these native events (with the associated top-level type used to
* trap it) to `EventPluginHub`, which in turn will ask plugins if they want
* to extract any synthetic events.
*
* - The `EventPluginHub` will then process each event by annotating them with
* "dispatches", a sequence of listeners and IDs that care about that event.
*
* - The `EventPluginHub` then dispatches the events.
