Steps to reproduce:
1. Edit 'Editor' role as in the picture
2. Add new 'Editor' user and log in
3. Go to Landing Page
4. Try to add blocks

Actual result:
User is able to add LP blocks

Expected result:
User should not be able to add LP blocks, becasue of field group 'Content' limitation.
(Tbh this should be looked at (& confirmed) by someone from backend) .
