/**
* Summary of `ReactBrowserEventEmitter` event handling:
*
* - Top-level delegation is used to trap most native browser events. This
* may only occur in the main thread and is the responsibility of
* ReactDOMEventListener, which is injected and can therefore support
* pluggable event sources. This is the only work that occurs in the main
* thread.
*
* - We normalize and de-duplicate events to account for browser quirks. This
* may be done in the worker thread.
*
* - 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.
