Building some custom widgets on top of jQuery UI, now when I try to destroy jQuery UI Dialog on top on which I have my widget, I see in FireBug that corresponding elements get stacked on top of html element.

I've attached a screenshot.


Is it how it is meant to be? Why?

I noticed similar behavior in the past with jQuery effects. Could not find a reason to it though, so I thought it was just my fault, of some kind.
