1. Open the profile of a user in a joinable world
  2. Click on the world card in the top right of the UI
Expected outcome: the world page of the instance the user is in pops up
Actual outcome: nothing
This is a regression in the UI. You used to be able to select the world card and it would open up the world page prior to this UI update.
Much like how the "Current Avatar" widget in the new UI works, the world card should also be a button to open the page of the world that a user is in, provided that it is not a private one.
