Yeah, I saw this case pop-up in a thread about misissuance of TLS certs
with onion addresses last month[0] and there was a specific case
including a v3 address [1]. Sorry, I should've sent an email about this.

So this may be a combination of needing new functionality on the
CA-side, plus needing controller support on the tor-side (unless they
wrote their own), plus whatever else is missing.
