When scaling maps in a cartography table using a filled map and a piece of paper, the resulting map shows its ID, scale and level as unchanged from the input map. The number of NBT tags does/can change
The created map is scaled correctly and shows details correctly once it is in the inventory, so I believe it is only a cosmetic issue in the cartography table. Screenshots show details including advanced tooltips of the input map and the output map.
Environment
Minecraft Java Edition, Windows 10 x64 version 1903
