Bug description

Enable RBAC, share a dashboard with a role.
Share -> copy permalink
Open that link on a private tab (or log out before)
Error {"error": "Error: You don't have access to this dashboard."} instead of redirecting to the login page.
When using a regular link instead of a permalink, the user is redirected: #30380

Before: {"error": "Error: You don't have access to this dashboard."}
