That's a false positive though. It does the same thing with this:

var x = (function () {
  return new Promise(function (resolve, reject) {
    reject(new Error("foo"));
  });
}());

When you could later on attach an error handler to x. We are starting
to favor false positives in order to get somewhat immediate error
logging. Also none of this helps production code unless we also have
something like onUncaughtPromiseException?
