It appears that SmithingRecipe ignores ItemMeta.

See the code example here: https://paste.md-5.net/qabajicuko.cs

In-game the item looses all it's NBT data, so the name I set in the item meta is lost. See screenshot in attachments

Expected behavior

Item gets the NBT data applied to the item stack when created.

Real behavior

Item looses it's NBT data when crafting
