When executing a command from a book inside a lectern, instead of executing it in the coordinates of the lectern, it uses the coordinates of the entity reading the book, unlike when executing commands from a sign that uses the coordinates of the sign.
This bug makes it more difficult to use the lectern for mapmakers to use it as a fixed point to calculate relative coordinates.
Steps to reproduce:
- Place a lectern containing a written book with a "run_command" clickEvent:
- Open the book on the lectern while standing a short distance away from it
- Click on the word "Test"
→ A block of stone is placed above your head (rather than above the lectern)
