Looks to me like the TLS client hello is being lost, which is why the server is sending duplicate SYN+ACKs.

No. To repeat: the client is sending a pure ACK with no data. You can see that packet with a 0 byte payload length in the screenshot. That packet is also getting lost; if it weren't getting lost, we'd be receiving a SYNACK.
