Correct.

This part is misleading: Modern Squids _automatically_ bump connections
to report [access denied] errors -- no explicit bump action is required
(or even desirable). I do not know whether

* that bumping does not happen for leo (e.g., due to Squid bugs), or

* it does happen, but the browser refuses to show the error page anyway
(because of certificate pinning and/or because Squid did not have enough
information to properly bump the client connection using just step1
knowledge).

A packet capture or an ALL,2 cache.log may distinguish those two cases.
