Bug Description

Display Entities, which was introduced in 1.19.4 and which allows better for example nametag formatting, make player nametags invisible below 1.19.4 while using ViaVersion.

Expected Behavior

I case of nametags they should be replaced by default ones if are impossible to display, to show them just like in vanilla minecraft.

Additional Server Info

This server is running Purpur version 1.21.5-2450-HEAD@61d7f55 (2025-06-17T05:07:48Z) (Implementing API version 1.21.5-R0.1-SNAPSHOT)

• You are running the latest version

Using 1.21.5 because not everything is stable on 1.21.7

Checklist

• Via plugins are only running on EITHER the backend servers (e.g. Paper) OR the proxy (e.g. Velocity), not on both.
• I have included a ViaVersion dump.
• If applicable, I have included a paste (not a screenshot) of the error.
• I have tried the latest build(s) from https://ci.viaversion.com/ and the issue still persists.

Cannot reproduce with the plugin you linked. There's issues with line breaks but that's a separate thing

Hello. Can you please how did you try to reproduce it?
I simplified everything to absolute minimum (added simple text "test" without any formating, all default values) and it still doesnt display anything.

Here is the view on 1.18.2 version (below 1.19.4 where this feature was added) - nothing visible above player head

And how it should look like (view from 1.21.5):
