Custom model data commands not working properly on 1.21.4 build 97

[Zenologia]

Expected behavior

When I run the command:
/minecraft:give Zenologia minecraft:paper[custom_model_data={strings:["bandana1"]}], i expect to see a piece of paper with a custom texture called on from a resource pack.

The attached screenshot is in a 1.21.4 SINGLE PLAYER world with the resource pack in place

Observed/Actual behavior

I get a piece of paper with one more entry for component data, but not the correct texture, and not marked as an "ingredient" with advanced tooltips on.

The following image is from a paper 1.21.4-97 server

Steps/models to reproduce

1. Enter world with resource pack loaded (either in local files in single player, or through server.properties for the server
2. Run the command /minecraft:give Zenologia minecraft:paper[custom_model_data={strings:["bandana1"]}] on the server, or /give Zenologia minecraft:paper[custom_model_data={strings:["bandana1"]}] on the single player world

Plugin and Datapack List

n/a - we removed all plugins and datapacks for testing purposes

in the future, you can also use a pastebin like https://pastes.dev

[Zenologia]

got it ok sorry. anything else you need from me on this ?

[Zenologia]

just fyi still happening with build 107

[lynxplay]

I cannot reproduce this on a fresh environment.

[Zenologia]

what i noticed is that the piece of paper has the same 9 component data on single player vs multiplayer, but the texture does not render in multiplayer. videos attached are named for the testing, and Ive included the sample resource pack that im testing with.

command ran on server:

/minecraft:give @p minecraft:paper[custom_model_data={strings:["bandana1"]}]

command ran in single player:

/give @p minecraft:paper[custom_model_data={strings:["bandana1"]}]

1.21.4 test rp.zip

video files were too large to attach - please see drive link

[lynxplay]

Can you sanity check this without mods and other resource packs installed?
E.g. a vanilla client without resource packs like vanilla tweaks etc.

[Zenologia]

https://drive.google.com/file/d/1ueM5LtbQUmtaW3aodVAX64Kk0-KeILof/view?usp=sharing

Sanity Check as requested. First part is single player then I go to the same testing server - which before this video I updated to 1.21.4-111 with the same result

[lynxplay]

Even tested this with a server supplied resource pack, I cannot reproduce this.
Other triage members also were not able to reproduce this either.

There is not much we can do here if we cannot replicate this issue.
I guess ensure the pack sent from the server is up to date?

Given I cannot replicate this, I'll be closing the issue.
Obviously sorry for closing this as you obviously experience some issue, but the github bug tracker is not really the place to debug your personal setup.
Can ask around in paper-help on our discord, maybe someone wants to run through some more potential pitfalls.
