The bug
When you use an empty map in creative mode to create a filled map, it will replace/consume the empty map instead of giving you a new map. The java edition also had this bug and it got fixed. MC-11532 This is also inconsistent with the behavior that happens when filling glass bottles with water in creative mode.
How to reproduce:
Make sure to be in creative mode
Get an empty map
Right click it
Observed Results:
The empty map was replaced with the filled map.
Expected Results:
The empty map should stay in the inventory and you should get a new map, because you are in creative mode.
