bug with modal window and desktop widget

Question

(sorry my english!) I use a modal window within a Tabview's page.

Check this little playground example.

Open the modal window, go to Second page, and return to First page. How can i solve this problem with the opened modal window? I need switch to other pages, return to the modal window's page, and close the modal window. I've been trying to figure this out. The Widget Browser application, from Qooxdoo website have the same problem, with the Window page example.

Thanks.
