Forge added "nbt" to "result" of vanilla datapack recipe, so as to support NBT crafting.

This is effective in 1.20.1 and below. But in 1.20.2, it doesn't seem to work, even though Forge Documentation says it can work.(Forge Documentation)

Like this JSON:

{
  "type": "minecraft:crafting_shaped",
  "pattern": [
    "BB ",
    "   ",
    "   "
  ],
  "key": {
    "B": {
      "item": "minecraft:blaze_powder"
    }
  },
  "result": {
    "nbt": "{Enchantments:[{lvl:2s,id:\"minecraft:protection\"}]}",
    "item": "minecraft:diamond_sword"
  }
}

In 1.20.1 and below, it can take effects as it should be. However, in 1.20.2, it's not effective at all.

Is this a bug? Or it works as intended?

Added:

Behaviors in 1.20.1 and below are, the json create a recipe that can craft the item with all the specified NBT;

Behaviors in 1.20.2 and above are, the json create a recipe that cannot craft the item with any specified NBT.
