Description
Latest jessica client's feature ".figure" crashes bungeecord quite fast (no errors, it just restarts), if there are at least 2 players online.
That feature sends item packets containing shulkerboxes that have books with oversized pages (too long and too many) inside. Seems like a workaround on the now already fixed oversized book exploit.
I think this should be prevented directly on waterfall, because only bungeecord crashes, while the spigot server is fine.
I was able to block this on spigot by checking packets via protocollib's api (viaversion and other common ways to block that kind of packet does not work sadly), but having a proper fix inside bungeecord would be better imho.

Research direction
Reproduce the crash using the Jessica Client’s .figure feature with at least two players online, then inspect Waterfall’s handling of item packets containing shulkerboxes with oversized book pages. Done means the proxy no longer restarts on these packets while ordinary item traffic and the backend server continue working.
