"""Respawning in a hardcore world on a dedicated server, against vanilla's, seen by a vanilla client.

A vanilla dedicated server and Horizon's (`horizon-client --dedicated --nogui`) each serve a copy of one hardcore
flat world vanilla generated first, with Alice an operator in survival. LocatorBarClient (a player made of
vanilla's protocol code) joins, runs /kill on itself and presses the death screen's button
(ServerboundClientCommandPacket PERFORM_RESPAWN). Vanilla's ServerGamePacketListenerImpl.handleClientCommand
respawns the player, then makes it a spectator because the server is hardcore. The game mode changes and respawns
Alice is sent in the death and respawn steps are compared exactly.
