After creating custom Monster Spawners for Husks or Strays, they didn't works on version 1.11 and later. Small preview figure rotate inside spawner, correctly reacting on player in Required Player Range. All other custom spawners work normally (witches, wither skeletons, zombie pigmens, other...)

/setblock ~0 ~1 ~0 minecraft:mob_spawner 0 replace {SpawnData:{id:"minecraft:husk"}}

In vanilla minecraft all works fine.
