Dropdown scrollable in IE

[ricopauw]

Hi,

It is currently not possible to use the mouse (point&drag the slider) in Internet Explorer. When the slider is clicked to start dragging the combobox is closed. It works like a charm in Firefox and Chrome.

Reproducable by opening the examples page in IE, go to ComboBox, unselect Albania to have a long list and interact with the combobox scrollbar. I guess it has something to do with the flex styling, but i'm not able to make it work for IE.
