  // invokeGuardedCallback uses a try-catch, all user exceptions are treated
  // like caught exceptions, and the DevTools won't pause unless the developer
  // takes the extra step of enabling pause on caught exceptions. This is
  // untintuitive, though, because even though React has caught the error, from
  // the developer's perspective, the error is uncaught.
  //
  // To preserve the expected "Pause on exceptions" behavior, we don't use a
  // try-catch in DEV. Instead, we synchronously dispatch a fake event to a fake
  // DOM node, and call the user-provided callback from inside an event handler
  // for that fake event. If the callback throws, the error is "captured" using
  // a global event handler. But because the error happens in a different
  // event loop context, it does not interrupt the normal program flow.
  // Effectively, this gives us try-catch behavior without actually using
  // try-catch. Neat!

  // Check that the browser supports the APIs we need to implement our special
  // DEV version of invokeGuardedCallback

/**
 * 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.

 * We listen for bubbled touch events on the document object.

 * Firefox v8.01 (and possibly others) exhibited strange behavior when

 * 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

 * 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
