Steps to reproduce:
1. Define site accesses and their groups as shown below:
2. Define site accesses' scopes and shown below:
3. Go to [host]/admin2/content/location/42 - notice the content tree info: This location has no sub-items
4. Go to [host]/admin/content/location/42 - notice the content tree highlighted folder
Invalid content tree render in admin2 site access
The result of previewing content tree as admin2 site access should be the same as a result of previewing the admin site access content tree as there should be fallback to group settings.
