Chaining HAProxies and the proxy protocol

I need to (temporarily) chain HAProxies (HAP A has connection issues with some backends)

HAP A -> HAP B -> backends

in HAP B, this works:

bind *:8080 accept-proxy

    acl lb src <ip>
    acl lb src <ip>
     tcp-request connection accept if lb

tcp-request connection expect-proxy layer4 if lb

    tcp-request connection reject


But the expect-proxy line (without the accept line), does not work with or without accept-proxy in the bind line.

Reading the docs, I expected the combination expect-proxy without accept-proxy to work. Is there a correct way?
