Advanced Frontend Editing:
When adding (drag drop) a new mailform, then saving (not closing) - even without changes. Then open the form wizard, try to clos (close icon top-left corner in ajax window) - dos not go back to the mailform detail window.

If editing an already existing mailform it works.

- Open Site in advanced frontend edit mode.
- drag a new mailform to a place > opens ajax window with form details
click on "save"
- then click on the "formular"-tab
- click on the form wizard > form wizard opens in ajax window
click on the close icon in the top left of the ajax window -> does not switch back to the form details view.
