-Subject: [PATCH] Process NMS Data Conversion post ItemMeta on Copy
-
-ItemMeta apply is a destructive process that expects to be the authority on
-what the items NBT data is.
-
-When CraftItemStack.asNMSCopy was called, the conversion ran, potentially setting
-the converted data into the ItemStacks tag.
-
-Then if that item had ItemMeta, it would completely undo that conversion by
-erasing the NBT Tag.
-
-On copy, run conversion post ItemMeta apply.
