------------------
- Avoid using a mutable default argument in the FolderContentsTable code. In a
LinguaPlone environment after viewing the folder contents of a collection,
the language of that collection got stuck as a content filter and wasn't
reset anymore. Viewing the folder contents of any item in a different
language showed an empty table until the Zope instance was restarted.

- Use the folder as the factory expression context when a front-page
is used as the display for the folder. Tests in `plone.app.contentmenu`.
