TCP RST is indeed considered a transient failure, and the RFCs specify that it should be retried several times before giving up.

My ad blocker returns "0.0.0.0" for A records, which in practice means attempts to connect to 127.0.0.1, which isn't running a server of any kind on port 443/tcp or 80/tcp. So a standards-compliant client would really hang awhile, or hold rendering, until several connects have been attempted and they all failed.
