TLS tickets shared among peers?

Hi, I have a “stupid” TCP reverse proxy which only does round-robin and sends requests to a cluster of 3 HAProxy I have full control of.
I have used the peers option to share stick-table among them, used to have proper shared request rate filtering.
Qualsys SSLTest reports that TLS tickets are offered but not honored, which I guess is because each requests lands on a different HAProxy.

Session resumption (caching)	No (IDs assigned but not accepted)
Session resumption (tickets)	No

Is it possible to do something among peers?
Or other solutions?
(or am I confused and TLS tickets have nothing to do with “session resumpion (caching)”?)
