+/**
+ * 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.
+ *
