Locked maps don't work using CIT. (Change textures)

[sadlittletree]

The bug:
When I lock a map in a cartography table its texture won't change, with the properties and the image file, I was trying to port Bedrock's locked map to Java.

Steps to Reproduce

1. Download Bedrock Map from Vanilla Tweaks, unzip the pack and check the properties file, opening optifine folder, and the cit folder.
2. Lock a map using the cartography table, make sure you have OptiFine installed and have applied the VT pack.
3. See it won't change.

    • Forge/Fabric and remaining mods, without OptiFine --> Yes, it is OptiFine issue.

Items with Lore in Vanilla work differently than items with lore from commands. Things like written books, maps, potions, etc. don't work with nbt.display.Lore, even if the vanilla lore matches what would be given through a command. I assume it has something to do with the tags on those items, but I don't know the technical details.
