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
