When crafting or otherwise obtaining items with the inventory GUI open, recipes and advancements are acquired/unlocked instantly. When most other GUIs are open, they are not granted until the GUI is closed.
GUIs tested: ✓ = Grants instantly, ✗ = Granted only when closing GUI
✓ Player Inventory
✓ Sign
✓ Writable Book (Book and Quill)
✓ Command Block/Structure Block
✓ Pause Menu (game menu, options, resource packs, etc)
✗ Crafting Table
✗ Brewing Stand
✗ Anvil
✗ Enchanting Table
✗ Beacon
✗ Hopper
✗ Dropper/Dispenser
✗ Chest/Trap Chest/Ender Chest/Shulker Box
It looks like this bug may affect GUIs that have their own inventory. Other GUIs such as Sign and the player inventory are unaffected.
