Describe the bug
Dev build for 1.17 does not allow to display maps inside of fake item frames.

To Reproduce
Send spawn entity itemframe to player and then populate it (using id) with an filled_map ItemStack.

public static void populateItemFrame(Player p, int id, ItemStack map) {
        PacketContainer pc = ProtocolLibrary.getProtocolManager().createPacket(PacketType.Play.Server.ENTITY_METADATA);
        pc.getIntegers().write(0, id);
        WrappedDataWatcher watcher = new WrappedDataWatcher();
        watcher.setEntity(p);
        watcher.setObject(7, WrappedDataWatcher.Registry.getItemStackSerializer(false), map);
        pc.getWatchableCollectionModifier().write(0, watcher.getWatchableObjects());

        try {
            ProtocolLibrary.getProtocolManager().sendServerPacket(p, pc);
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
}

Expected behavior
Item frame filled with a map.
