Bug Description

My client crashed when the server sent it an invalid packet with an armor rack (hologram)

Steps to Reproduce

1. Connect to the 1.16.5 server from the 1.12.2 client.
2. Try to create a hologram.
3. Your client should crash after this.

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 a build from https://ci.viaversion.com/ and the issue still persists.
