url-retrieve should use CONNECT when talking to a https URL over a proxy
and then talk over the connection as if not using a proxy.
;; use locally running privoxy as proxy
(setq url-proxy-services '(("https" . "localhost:8118")))
(with-current-buffer (url-retrieve-synchronously "https://www.heise.de")
(buffer-string)) => "HTTP/1.1 200 Connection established\n\n"
Andreas.

Is this identical to #11788? If so, this is fixed only on master because
it was deemed too risky for emacs-25. I'm still of the opinion that this
is a serious security issue, because of the possible silent fallback to
http without the user noticing. I'm always running my Emacs with
3c623c26a manually backported.

I tried this with tinyproxy and Emacs 27, and it worked for me, so I'm
guessing this has been fixed in the meantime, and I'm closing the bug
report.
Please reopen if this is still an issue.
