Description
This problem was discovered a long time ago. In order to verify it, I specially collected baby drowners, but I didn't find one with the trident.
The whole collection process is in the link. I have speeded up the video processing. If the process is boring, you can skip to 3: 05.
This may be intended, because the entity_spawned event in the drowned.json behavior file explicitly randomizes randomizes between adult (95%) and baby (5%) only under the mele option (85%). The ranged option (15%) has no sub-option for baby.
