What exactly is the bug you are experiencing here? Listening to packets is not part of the Paper API. If something behaves weirdly there or breaks, its due to whatever you or ProtocolLib are doing with that packet. I am also not really able to see any obvious issue in your video.

Generally, the server will send inventory packets more often than required in a lot of cases to reduce the potential of desync, so just the ClientboundContainerSetSlotPacket getting sent while not required is not something that needs to be fixed. We also would need to rule out that this is a ProtocolLib issue - sometimes just listening to a packet can have weird side effects. You could use a client-side packet logger for that.
