Some Explorer Maps are missing their icon

The bug

If an explorer map leads to a location very near to the map's border, the structure icon won't appear on the map at all.

How to reproduce

1. Create a world with seed 467491214708786261
2. Spawn a cartographer:

   /summon villager ~ ~ ~ {VillagerData:{profession:cartographer,level:3}}

3. Purchase a woodland explorer map
   → The map has no mansion icon
