Bug when switching tab

[ping0]

I think I have found a bug in the dropdownlist demo:

http://demos.kendoui.com/web/dropdownlist/index.html

Tested with chrome. If you click on the dropdownlist control, the list shows up, now while the list is open, switch to another Chrome tab and then come back. Now the control acts weird, when you click on it it opens and closes immediately.

So if you switch tab while the dropdownlist is open, somethign breaks.

Yeah I've found the same bug in chrome browser. I was trying to create my own dropdownlist using  http://cdn.kendostatic.com/2012.2.913/js/kendo.all.min.js and I got the error described before, I supposed that it was because of my code, so I tested the online demo and I got the same behavior. Also I've tried with the example from the download package and I couldn't reproduce the error, but there is another bug, when the list shows up, the items get stuck in the visualization and the selected item has some layers with the prior selections.

This also exists with the date picker control.

It seems it also happens too, whenever you leave focus of the window - via tabbing or by moving your mouse to a new window, or alt-tabbing.
