I have an `iframe` and I need the scrollbars to be present even when content fits inside the `iframe`. so used `overflow:scroll` property . which works fine for FF, IE but not in chrome.

```
#iframeid
{
    height:500; width:1150
}
#iframeid::-webkit-scrollbar
{
    width: 12px;
    overflow-x:scroll;
    overflow-y:scroll;
}

```

this totally removes the scrollbars. Any thing I am missing ?
