You can continue to walk if killed in game-ending kill

On the A.E.S. server since about 8/8/2023, if you get killed and this kill ends the game, you can continue to walk around as if nothing happened (you don't join spectator or get eliminated). The correct game result messages are shown, but you don't look dead at all.

This is a regression because it used to work properly a few days beroe.

Not sure if this is a bug in Murder or arena_lib or something else.
