CSRFGenerateToken not working with sessioncluster and sessionstorage

I’m trying to use the CSRFGenerateToken/CSRFverifyToken but with our conf doesn’t work: we have sessioncluster = true and a sessionstorage configurared (memcached)

I see that there are a bug report about sessioncluster=true not working but it works with forceNew=true option, but if you have sessionstorage set, doesn’t work. Ticket: https://luceeserver.atlassian.net/browse/LDEV-784

So, there is a workaround with this conf, or should I open another bug report ?
