"type=creaking" does not find naturally spawned creakings

It is not possible to target naturally spawned creakings specifically in a target selector.

To reproduce

1. Find a naturally spawned creaking in an area with no other nearby mobs

2. /teleport @n[type=creaking,distance=..2] ~ ~ ~

   The command fails

3. /teleport @n[type=!player,distance=..2] ~ ~ ~

   The command succeeds
