[BUG] About the refresh of the page permission cache

@fsbraun

djangocms: 4.1.1

Create a user group
Add the user to the user group
In the advanced settings of the page, add the user group for View restrictions
At this point, the user should have permission to browse the page.
However, the user will see a 404 page (insufficient permissions)
Restart the service 'python manage.py runserver'
Users can access it normally

I'M NOT SURE IF IT'S INTENTIONAL DESIGN, OR IF IT'S A BUG. My current solution, though, is to manually flush the cache

from cms.cache.permissions import clear_permission_cache
clear_permission_cache()
