How to get IE 10 to show all options in a long datalist

Question

I have a situation where I'm using an HTML Datalist and text input for users to select or type in a state, where there are a long list of options. Firefox and Chrome will enable a scrollbar to be able to select options further down the list that aren't initially visible. In Chrome this ability is enabled when you use the autocomplete="off" attribute. IE 10 unfortunately doesn't show a scrollbar in any case that I'm aware of, so the user can't see or select what is initially visible, even if they attempt to key down to the bottom of the list.

Does anyone know of a solution to get IE 10 to show a scrollbar on a very long datalist?

You can see my example on JSFiddle:
