     *    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.

     *
     * Firefox v8.01 (and possibly others) exhibited strange behavior when
     * mounting `onmousemove` events at some node that was not the document
     * element. The symptoms were that if your mouse is not moving over something
     * contained within that mount point (for example on the background) the
     * top-level listeners for `onmousemove` won't be called. However, if you
     * register the `mousemove` on the document object, then it will of course
     * catch all `mousemove`s. This along with iOS quirks, justifies restricting
     * top-level listeners to the document object only, at least for these
     * movement types of events and possibly all events.
     *
     * @see http://www.quirksmode.org/blog/archives/2010/09/click_event_del.html
     *
     * Also, `keyup`/`keypress`/`keydown` do not bubble to the window on IE, but
     * they bubble to document.
     *
     * @param {string} registrationName Name of listener (e.g. `onClick`).
     * @param {object} mountAt Container where to mount the listener
