Issue link redirection not working for Atlassian Account customers

Summary

When Atlassian account Jira Service Desk customers access the link to a Jira Issue that they have access (https://site.atlassian.net/browse/KEY-1), they are not being correctly redirected to the respective portal link of the request (https://site.atlassian.net/servicedesk/customer/portal/1/KEY-1).

Steps to Reproduce

1. Create an Atlassian Account Jira Service Desk customer (Atlassian account without any application access)
2. Logged in as the customer, create a ticket in a Jira Service Desk project.
3. Copy the issue URL and paste in a comment on the ticket. (This should render the "Agent URL" of the ticket)
4. Click on the issue link

Expected Results

The page reloads and you'll be redirected to the same ticket.

Actual Results

You'll be redirected to the Help Center (https://site.atlassian.net/servicedesk/customer/portals)

Notes

This doesn't affect portal only accounts.

Workaround

• Access the ticket via "Requests" in the top-right corner of the screen.
