MSDN says IE11 should use "onload" for script tags. What about this?

```js
if (msie) {
  script[script.onreadystatechange ? 'onreadystatechange' : 'onload'] = function() {
    if (/loaded|complete/.test(script.readyState)) doneWrapper();
  };
}
```

Or is it okay to just ignore it for IE11?
