Range slider (<input type="range" ..>) not working as a child of 'dragscroll'

Hi,

Seems like a range slider placed within dragscroll is not working.

E.g. for the code below the slider just freezes and you can't change the value:

```
<div class="dragscroll">
     <div class="slidecontainer">
        <input type="range" min="1" max="100" value="50" class="slider" id="myRange">
     </div>                              
 </div>
```

Thank you.
