There's a related problem where if the server's first flight goes missing, the only response the new logic has is to send a probe at unspecified, i.e. highest known, encryption level. The server will generally have 1-RTT keys at this point, so it sends a 1-RTT probe, which the client, not having received anything prior, cannot decrypt and drops.
