Customers can see the KBs that are allowed anonymous access when they are not logged in to JIRA Service Desk portal. Once they log in to the JIRA Service Desk portal, however, they can't any longer view the KBs(if they don't have access to the portal). 

Steps to Reproduce

1. Create a JSM portal 
2. Link to a Confluence Space
3. Make that space available anonymously
4. Ask a customer to open that link(don't invite them to the project)

Expected Results

The publicly accessible project issues should be accessible in both cases i.e. When the portal-only customer account is logged into the portal or not logged in.

Actual Results

The publicly accessible project KBs are available only when the customer is not logged in to the portal.

Workaround

A possible workaround could be to use two different browsers until this bug is fixed. One browser window to login to the portal and another browser to view the public issues. Alternatively, the same browser can be used with one standard window and another private browsing (incognito) to view public issues.
