Holograms don't seem to get translated on vanilla/normal servers in 1.8->1.7

Bug Description

When creating an ArmorStand using:

ArmorStand stand = (ArmorStand) world.spawnEntity(world.getSpawnLocation(), EntityType.ARMOR_STAND);
stand.setSmall(true);
stand.setVisible(false);
stand.setMarker(true);
stand.setCustomNameVisible(true);

The hologram emulation breaks and will show only the zombie rather than the zombie/skull combination

Steps to Reproduce

1. Create a 1.8.8 spigot server
2. Install a plugin using the code Above + VV/VB/VR
3. Join with an 1.7.10 client on the server

Expected Behavior

The holograms should be converted as usual.

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.
• I have looked at https://www.spigotmc.org/resources/viarewind-legacy-support.52924/ and it does not offer a fix for my problem
