Despite them being books, knowledge books can't be placed in a chiseled bookshelf.
How to reproduce:
Give yourself a knowledge book (
/give @s minecraft:knowledge_book)Use it on a chiseled bookshelf
Expected behavior:
The knowledge book is placed in the chiseled bookshelf
Actual results:
Books are retrieved from the bookshelf (if present), or nothing happens if the bookshelf is empty.
Just to clarify, the hand animation plays here because of MC-256470 but no knowledge book is placed onto the chiseled bookshelf. I can confirm this behavior.
