The issue is reproducible with the recently released wolfSSL 5.7.2 and with curl instead of Privoxy as well.
Reproduction steps
Build Privoxy or curl with wolfSSL support and try to access https://traxxas.com/.
Note that wolfSSL support for Privoxy is only available in git master.
The log output below has been created with curl configured with: ./configure --with-wolfssl --disable-shared --enable-debug --enable-maintainer-mode
and curl patched by adding: wolfSSL_Debugging_ON();
before: ret = wolfSSL_connect(backend->handle);
in curl's lib/vtls/wolfssl.c.

Thanks for the in-depth report, I will work on reproducing and debugging this tomorrow.
One thing I did notice is you are not passing in --enable-tlsx to your ./configure line, this enables all supported TLS extensions. You are enabling some of them but not all of them. Missing TLS extensions can cause issues like what you're seeing, so it's worth trying to enable them.
Thanks for the quick response and the tip, @kareem-wolfssl.
I was unaware of `--enable-tlsx` and will use it in the future
instead of `--enable-tls13-draft18`.
It doesn't seem to make a noticeable difference for connections
to https://traxxas.com/, though.

Version
5.7.2 and 5.7.0
Description
SourceForge user withoutname reported in Privoxy SF bug #1765 that Privoxy 3.0.35 can't establish TLS connections to https://traxxas.com/ when linked to wolfSSL 5.7.
It works with OpenSSL and MbedtTLS.
The issue is reproducible with the recently released wolfSSL 5.7.2 and with curl instead of Privoxy as well.
Reproduction steps
