When crafting a Map with Zoom the result is a blank map.
1)Craft a Empty Map
2)Create Map
3)Place the new Map in the Anvil with 8 pieces of Paper
4)Push the "result" field in the Avil interface
The Anvil do not play a sound and the resulting Map is blank.
Tested this both in Creative and Survival Mode with identical results.
Tested it in "Local" World were it works as intended so issue is likely confined to Realms.
