The bug
The following is based on decompiled version of Minecraft 1.9 using MCP 9.24 beta. All method and class names are the names used in the decompiled version.
Based on the code a baby being born should create heart particles. However, this is not the case. See method net.minecraft.entity.ai.EntityAIMate.spawnBaby().
