- Visit https://phabricator.wikimedia.org/project/board/67/ (I guess any board will work).
- Find a card that's not assigned to anyone.
- Click on the pencil icon that's on the right of the card.
- In the edit popup, assign the card to someone and save.
- In the column where the card was, you'll see another updated card with the same name.
Expected:
- Only the updated card should show, the old card should disappear.
