Lectern flashes GUI when 'has_book: true' and no book present in data
When you right click on a Lectern with 'has_book: true' property, the game attempts to open the written book GUI despite there being no book present in its data.
Steps to reproduce:
1. Run
/setblock ~ ~ ~ minecraft:lectern[has_book=true]
2. Right click the Lectern
I use this in custom content for my datapack. This is distracting and an epilepsy risk so I would like to see this fixed.
