Internal Exception when raid starts

When entering a village with the Bad Omen effect, the client instantly disconnects from the server, giving the following message:

 

Internal Exception: io.netty.handler.codec.DecoderException: java.io.IOException: Packet 0/12 (class_2626) was larger than I expected, found 51 bytes extra whilst reading packet 12

 

Untested while playing locally. Untested with snapshot 19w34a.

Upon switching to release 1.14, I have confirmed that the bug does not exist in that version.
