BUG: Checklists not created at correct position

,

I’m using the one I referenced in the OP.
It’s definitely (still) not working, as it always creates it at the bottom:

My request is:

curl --request POST \
  --url 'https://api.trello.com/1/cards/6j8TDwj6/checklists?name=test&pos=top&key=MyKeyHere&token=MyTokenHere'
