Expected behavior

I expect the Lectern to not appear while utilizing the MenuType and builder API

A Lectern appears in the world

Steps/models to reproduce

Create a lectern with the API. And it will appear at the player's location

LecternView lecternView = MenuType.LECTERN.create(player);
lecternView.setPage(3);
lecternView.setItem(0, item);
lecternView.open();

Other

Using a second player I confirmed the following behavior. A lectern appears under the following cricumstances.

• If Player1 creates a Lectern InventoryView from the MenuType API
• While having the lectern open if Player2 destroys the lectern that appears after Player1 opens it a page change occurs a new lectern appears
• Any State change to the lectern will cause the lectern to re-appear

Comes down to most likely these two methods
LecternBlock#resetBookState -> Creates the block upon book insertion or removal
LecternBlock#signalPageChange -> Creates the block again upon page change

Start with LecternBlock#resetBookState and LecternBlock#signalPageChange, using the MenuType.LECTERN and LecternView reproduction in the issue. Trace how book insertion, removal, page changes, and other state changes create the lectern block. Done means the MenuType API view remains usable without a lectern appearing at the player's location.
