Well when you tame a wolf, and name it using the Nametag item, if the wolf get killed by something, it will output a death message saying the wolf has been kill from the thing that killed it.
Client Side. It also happens in Servers aswell.
My theory for this is it is using a new entitiy in minercaft called "ArmorStand". So these text above and below players in tab list is called Header and Footer and which I see it on Spigot Servers. What I think is that when a player press tab or has tab list open, a plugin checks for a player that has it open, making stacks of ArmorStands with DataTags of {Invisible:1,DisabledSlots:999999999,NoGravity:1,CustomName:"NAME",CustomNameVisible:1} getting teleported in front of the player in amount of distance. But it would not explain how the header and footer text still shows when going to singleplayer or a different server. Another theory I have is scoreboard. There could be an objective setdisplayed in list. The header and footer could be show as there is an NBTTag called "RenderType". By default, its integer. So unless there is other RenderTypes like maybe string, then that could be it.
Wow, I didn't know it was a feature. Thanks for telling me this you two.
