That’s the behaviour I’m seeing. For example, clicking the ‘read this topic’ link for https://meta.discourse.org/t/travis-tests-failing-due-to-eslint/163268 tries to take me to
https://meta.discourse.org/t/travis-tests-failing-due-to-eslint/163268/u/simon_cossar/preferences/notifications
instead of to https://meta.discourse.org/u/simon_cossar/preferences/notifications.
