I was trying to find which mobs could activate the sculk catalyst, and found that, the ender dragon activates it. I am reporting this bug because I think it might be accidental and shouldn't occur.
Steps to recreate
Place a sculk catalyst
type /summon minecraft:ender_dragon ~ ~ ~ {NoAI:1b}
then type /kill @e[type=minecraft:ender_dragon]
The sculk catalyst should activate
Why do you think that ender dragons should not activate the sculk catalyst?
