I have a problem with DropDownList that appears i think only in Firefox (FF ver. 28.0, even in safe mode).
The problem apperas even in Kendo official demo http://demos.telerik.com/kendo-ui/web/dropdownlist/index.html
Problem is that when i load page - dropdown works fine - but when i scroll down page, then dropdown doesn't work (i see the animation that dropdown is expanding but immediately dropdown list collapses).
