Steps to reproduce

If the URL https://tdstest.tennis.de/web/guest/kontakte is called up, a ZK portlet with a data box is integrated there. The controller outputs the current width of the screen. If you change to a different menu item and make the window smaller, the event will continue to be fired even though the ZK content is no longer in the DOM.

Current Result

The result is an error message "Desktop z5mo: /layout/xxx.zul] client error: processing failed _setAttra is undefined (TypeError) [Sanitized]"

Expected Result

Debug Information

A clientInfo-event is still trying to fire after removing a portlet containing ZK content
