/**
   * Summary of `DOMEventPluginSystem` 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 `EventPluginRegistry`, which in turn will ask plugins if they want
   *    to extract any synthetic events.
   *
   *  - The `EventPluginRegistry` will then process each event by annotating them with
   *    "dispatches", a sequence of listeners and IDs that care about that event.
   *
   *  - The `EventPluginRegistry` then dispatches the events.
