  * 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
- *    ReactEventListener, which is injected and can therefore support pluggable
- *    event sources. This is the only work that occurs in the main thread.
+ *    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.
