Honey block recipe is unlocked when honey block is obtained

For most recipes, the recipe is unlocked when the ingredient is obtained. But for honey blocks, it is unlocked when you obtain a honey block. i.e. there is no way to naturally learn this recipe in game without crafting it.

The advancements/recipes/decorations/honey_block.json file contains this condition as a criteria:

"has_honey_block": {
      "trigger": "minecraft:inventory_changed",
      "conditions": {
        "items": [
          {
            "item": "minecraft:honey_block"
          }
        ]
      }

It's probably meant to check for honey_bottle rather than honey_block
