Sorry about that. Should be:

```
  var bounds = element.getBoundingClientRect();
  hoverElement.style.left = (window.scrollX + bounds.left) + 'px';
  hoverElement.style.top = (window.scrollY + bounds.top) + 'px';
  hoverElement.style.width = bounds.width + 'px';
  hoverElement.style.height = bounds.height + 'px';
```
