Code analysis
Based on 1.11.2 decompiled using MCP 9.35 rc1
The method net.minecraft.inventory.ContainerEnchantment.transferStackInSlot(EntityPlayer, int)
only copies the complete item stack data if it has a count of 1, otherwise it creates a new item stack with count 1 and the same meta data but not the NBT data.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
Spawn eggs seem to work correctly in Minecraft 1.14.4, but the issue remains for firework rockets and tipped arrows.
Confirmed.
