When i give myself an item with the death_protection component and the play_sound field, it plays both the specified sound and the normal totem sound.
Steps to reproduce:
/give @s blaze_rod[minecraft:death_protection={death_effects:[{type:"minecraft:play_sound",sound:"minecraft:entity.ender_dragon.growl"}]}]Hold the item in your hand, then die (for example `/damage @s 1000`).
Both the ender dragon growl sound and the normal totem use sound will be played.
