tropical_fish_bucket tooltip not rendering specific fish

[catgirldoll]

Current Behavior:
the entity render in the tropical_fish_bucket tooltip defaults to a possibly untextured "kob" model regardless of NBT.
Expected behavior:
specific fish type rendered in tooltip, similar to axolotl variants in the axolotl_bucket tooltip.

Environment:
New Minecraft 1.17.1 instance
Fabric Loader 0.11.6
Fabric API 0.47.0+1.17
Inspecio 1.0.3+1.17
JRE 16.0.1

Logs and info:
MultiMC log
DXdiag dump

Video example
Video was taken in a significantly modded environment, but I tested in the fresh instance detailed above directly afterwards and the issue persisted. The MultiMC log is of the sanity check in the fresh instance.
