player esp does not show spectators

Wurst version: latest
Minecraft version: 1.21.1

Steps to reproduce:
1. got to a server
2. go near a friend in spectator
3. turn on player esp

yes i made sure i had filter invs off, although i tried it with it on as well

Sadly:
Invisible ≠ spectator

I am pretty sure the client doesn't even render or have any sign of the spectator player.

Arti oh, shame
