On the Java edition, when a sculk shrieker is placed down by a player it changes the "Can_Summon" to true so that a Warden is not spawned unless it is in natural terrain. On the bedrock edition, however, this tag is either not working or doesn't exist. This allows for people to spawn wardens anywhere and that doesn't seem to be intended. 

Steps to reproduce:

1. Place a sculk shrieker anywhere.
2. Activate it until a warden spawns.
