- Create page A.B.WebHome
- Set some permissions on page B.WebHome(this created B.WebPreferences)
- Export A.B.WebHome to XAR
- Delete space A.B (with children)
- Import XAR and verify that the permissions are not set anymore (the reason is because the WebPreferences page was never exported)
From an end user POV this is awkward and a solution is to always export the WebPreferences page when exporting a non-terminal page.
