While testing EZP-23725, I've found out that after publishing the "News" folder, using the frontpage will break the

content:
    tree_root:
        location_id: 142

setting.

Steps:

1. On the admin interface, create folder A
2. Inside folder A, create folder B
3. Take note of folder's B node_id
4. In ezpublish.yml, on the default site access, add
content:
tree_root:
location_id: node_id
5. Access to your site frontpage
6. Login
7. Edit "Folder" B and publish it
8. Instead of displaying folder B it will display folder A

Workaround
1. Login into admin interface
2. Edit folder B and publish it
