I'm not sure if it is related, but I am running into a problem using a dropdown in a window, when viewed on a mobile device (or more precise, a Chrome device toolbar's mobile device). I tried to prepare a dojo, but obviously it cannot be replicated without a "mobile dojo": http://dojo.telerik.com/OPeNo
The issue is that the dropdown is only about half the size it should be. It has to do with the
-webkit-box-sizing: border-box; / box-sizing: border-box;
attributes on span.k-input.
There is an html comment at the bottom, that helps reproducing the issue by replacing the k-widget class with km-widget.
