Is there a way to delay irssi's channel re-join during reconnect until after auth has occurred?

When I am connected to an invite-only channel and I experience a network outage, there's a race condition between automatic auth'ing and rejoining channels. (ETA: If it matters, I'm using CertFP (client SSL cert) to auth.) If auth is too slow, irssi removes the windows for invite-only channels. Is there a way to delay channel reconnect, or in some other way solve this race condition? (If I can't, as an alternative I would at least like to keep irssi from closing the windows!)
