  // functions in invokeGuardedCallback, and the production version of
  // 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
  // unintuitive, 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!
