What I expected to happen was...:
Chiseled bookshelves containing NBT data are normally displayed on the ground and in the inventory

What actually happened was...:
Chiseled bookshelves containing NBT data will not display normally (in the inventory and on the ground)

Steps to Reproduce:
1. Place a chiseled bookcase and fill in books.
2. Press Ctrl and the middle key to copy the chiseled bookshelf containing the filled book with NBT data. It is found that the filled book is not displayed in the inventory.

3. Place it on the ground and the book is not displayed.

4. Break it and the book will fall normally.
