The setTimeout fires after the modal already hides so it ends up firing twice which causes an error because the element is no longer there:
```
Uncaught TypeError: Cannot read property 'get' of null
at Popup.triggerEvent (storm-min.js?v443:3732)
at Popup.hide (storm-min.js?v443:3741)
at storm-min.js?v443:3730
```
