Giovanni Campagna 587655f063 Workspace: show attached modal dialog
Windows in the overview should be like they appear in the workspace,
including modal dialogs that are attached above them.
In addition, hiding the dialogs in the overview causes a flash as
dialog appears at the end of the transition.

Based on a patch by Maxim Ermilov <zaspire@rambler.ru>
