Behavior doesn't run in JSM Customer Portal for anonymous users (not logged in)

When using Behaviours for JSM Customer Portal, it doesn't get triggered for anonymous users (not logged in). This prevents use cases such as for public users raising tickets in a JSM Portal with public access.

Steps to Reproduce

1. Create a new Behaviour and map it to JSM project and all Request Types
2. Add Description field in and set it as 'Read-only'
3. While logged in, go to the mapped Request Type and confirm that the Description field is set as 'Read-only'
4. Log out, refresh the Request Type page and see that the Description field is no longer 'Read-only'
   This requires the JSM project to be set with public access

Expected Behaviour

The Description field is still set as 'Read-only' even for anonymous users

Actual Behaviour

The Description field is not set as 'Read-only' for anonymous users
