Links inserted in Civimail are not redirecting and require a log-in

This seems to have started with CiviCRM 5.27.0 on a Joomla installation. When using Civimail to send out an e-mail to our users, the link no longer redirects to the initial destination but goes to the Joomla Administrator log-in page. If you are logged in as an administrator, then the link works properly on the redirect. I’ve upgraded to 5.27.2 with the same result.
