cert error as overlap when they do not overlap

[davem-git]

I'm getting this error

The hostname *.subdomain.acme-dev.com overlaps with the hostname in listener https. ALPN will default to HTTP/1.1 to prevent HTTP/2 connection coalescing, unless explicitly configured via ClientTrafficPolicy

one listener has a *.acme-dev.com cert while the other listener has a *.subdomain.acme-dev.com. With how certificates work, these do not overlap. Yet i'm getting an error that they do. Does this seem like a bug, should i open an issue?
