BannerPatternsComponent not working

[dan28000]

Describe the bug
when using cursor to move a banner around in inventory and having a listener for WindowItems and reading items from that packet it visually clears the banner of any patterns this only happens on 1.20.5+

aside from that when doing this and checking components on the item when using cursor to move banner around it shows as BlockEntityDataComponent but when sending a custom WindowItems packet with banners inside from the server it shows as BannerPatternsComponent that are all empty

To Reproduce

1. register WindowItems listener
   example code

@Override
public void packetReceive(PacketReceiveEvent<WindowItems> e) {
     WindowItems packet = e.packet();

     short windowId = packet.windowId();
     int stateId = packet.stateId();
     packet.items().stream()
           .filter(Objects::nonNull)
           .map(BaseItemStack::getComponents)
           .forEach(System.out::println);
}

2. move any banner with patterns around in the inventory on the server using cursor
3. it should visually lose all patterns

Expected behavior
when moving banners around in inventory patterns should stay intact
