Texture doesn't change when formatting is different

I don’t know if this is intended, but formatting does not change the texture when renamed.

Steps to Reproduce:

1. Install any resource pack that has a feature that allows the texture of an item to change when renaming it that was made after 25w03a (e.g. Dynamic Names)

2. Get an item where the texture can change by renaming with the texture pack with commands and without italics

Expected Result:

The texture is changed.

Observed Result:

The texture only changes if the name is in italic, even if specified in the .json file.
