Virtual lectern does not work

[KabanFriends]

Describe the bug

When showing a lectern GUI of a lectern that does not exist in the world, bedrock players don't see the book text.

To Reproduce

1. Run a code like this to open a virtual lectern GUI:

Inventory inv = Bukkit.createInventory(null, InventoryType.LECTERN);
ItemStack book = new ItemStack(Material.WRITTEN_BOOK);
BookMeta bookMeta = (BookMeta) book.getItemMeta();
bookMeta.addPage("Example Page Text");
bookMeta.setTitle("Example Title");
bookMeta.setAuthor("Sigong");
book.setItemMeta(bookMeta);
inv.setItem(0, book);
player.openInventory(inv);

2. Observe the text in the book

Expected behaviour

Bedrock players can see the text "Example Page Text" correctly
