Book and Quil dupe does not work

[xDroflLOL]

Instead of the dupe working, you'll get Internal Exception: io.netty.handler.codec.DecoderException: Failed to decode packet 'serverbound/minecraft:edit_book', and when you reconnect, no items are duped. Possible class name change?
Tested on multiplayer, 1.21.4, and 1.21.3. Both versions do not work, 1.21.4 was tested on a small modpack on fabric, 1.21.3 was tested on vanilla.
Close this issue if the dupe has already been patched.
