Code analysis
Based on 1.12.2 decompiled using MCP 9.40
The method net.minecraft.item.ItemPotion.onItemUseFinish(ItemStack, World, EntityLivingBase) reduces the stack size before applying the potion effects and testing advancement triggers. Therefore when the triggers are tested 0*potion (acting like 0*air) is compared.
Reducing the stack size should probably happen right before the glass bottle is added to the inventory.
