The client crashes when crafting a zoomed out map using the output as an input.

Recreate:
1. Connect to server
2. Acquire a map
3. Acquire at least 16 paper
4. Activate craft table
5. Place map in middle tile and two paper in all other tiles of crafting table
6. Take the outputted map and place it back into the middle tile of the crafting table
7. Take the outputted map
8. Client crashes

This doesn't seem to happening in SPM. I do not have a vanilla MC server to test this out on.
