Moving dijit.Dialog or dojox..FloatingPane with dropped FilteringSelect

[guest]

Not sure whether it is an issue of FilteringSelect? or Dialog/FloatingPane?. But when you have a Dialog or FloatingPane? which contain a FilteringSelect? widget, the Selects dropdown list stays at its position (if dropped down) while you move the Dialog/FP by dragging its title bar. I think it should blur the FilteringSelect?, when one clicks the title bar, so that the dropdown list disapears. Even worse is, that when you have the dropdown opened and click the hide button in the FPs title bar, the FP fades out, but the dropdown list stays at its position.
