While I was viewing an invisible warden in spectator, I noticed that its sensors on its head just disappeared and could only be visible when viewed from the front.
To repeat this,
summon a warden
splash it with an invisibility potion
go into spectator
view it from the back and see that its sensors just vanish.

This behavior is not exclusive to spectator mode, and can be observed when on the same team as the invisible warden.
This also applies to the inner 'ribs' of the warden as well:

Can confirm in 1.19.1.
