[CIT] Values such as {"translate":"filled_map.manion"} in the item_name component don't seem to be detected in .properties

Description of Issue

I'm not sure the best way to explain this. But it seems that there is no way to have a CIT based on the {"translate":"value"} item_name component as shown in the image below

I have tried many different synaxes for it, and none of them seem to work.
I've concluded at this point that it must be an Optifine issue of some kind.

Steps to Reproduce

1. Create a new resource pack and create a .properties file in assets>minecraft>optifine>cit
2. Open the .properties file and write type=item matchItems=filled_map texture=map_mansion components.item_name={"translate":"filled_map.mansion"}
3. In the same folder where the .properties file is located, add a png file and name it "map_mansion.png"
4. Load the resource pack in Optfine 1.21.1 and obtain a Woodland explorer map from a cartographer villager

Additional Notes

I know this is probably missing some information, but I don't know what else I could include. If any other information is needed then please ask, I am not good at this sort of thing.

Just as an update, I tried it with CIT resewn on fabric and it works fine, just not on Optfine
