startAtIdle not working

[achilleus68]

It seems like the startAtIdle option is not working

See https://jsfiddle.net/jvddrift/ktso2h5p/2/ I'm using the example from the Wiki

$(document).idle({
  onIdle: function(){
    alert('It\'s been a long time since you don\'t see me');
  },
  idle: 30000,
  startAtIdle: true
})

I expect the alert to show directly at page load, because startAtIdle is set to true

However, the alert only just appears after the timeout period set (3000ms)
