Ender Dragon activates Sculk Catalyst

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
