Allow "Long text" mirror columns to display on multiple lines

When a long-text type field is mirrored on another board, we are not able to edit the vertical height of that field on the item view (when clicking the item and opening the side panel). This mirror column shows as a single line, rather than the adjustable multiline like on the source board. We’d like to be able to adjust the size of the mirror column on connected boards as well.

I agree, this would be a great addition to how we can customise item views to specific use cases.
