What is the expected functionality of archived items with linked boards?

I’m curious what the expected behaviour is for items that are linked to another board and have columns mirrored on that second board.

For example: I have a Team Sprint Board with items from multiple projects. There is a PTS column on the Team Board.

In the Project Roll Up Board, I link a project to all of the related items in a connected board column, then use a mirror column to SUM the PTS from the Team Board.

But it’s not clear what should happen when an item is archived. It seems to maintain the link (which works for my use case) but it doesn’t seem intended as it doesn’t actually say the item is archived when you view it from the Project Roll Up Board (see screenshot).
