[REALMS-9214] Renaming items has a long delay before the renamed item appears

Update on this issue:

Thanks for the reports! If this is happening for you, can you post your general location in the world (e.g. New Zealand)?

I can no longer rename name tags or other objects using an anvil as of the most recent update.

Steps to Reproduce:

make anvil
put an item in it
Rename

Observed Results:
Renamed item does not appear in the output slot, at least for 30+ seconds.

Expected Results:
Renamed item immediately appears in the output slot.

Note: This can only be reproduced in the realms, singleplayer works normally.
