## Description of problem:
TLS handshake fails when connecting to specific HTTPS servers after upgrading 
OpenSSL from 3.5.4 to 3.6.0.

It is definitely a problem caused by updating OpenSSL to 3.6.0 because if you 
roll back to 3.5.4, everything works again.

This was initially detected in WebKit applications, so there [is a related bug 
in Bugzilla](https://bugs.webkit.org/show_bug.cgi?id=300584).

## Version of gnutls used:
3.8.10

## Distributor of gnutls (e.g., Ubuntu, Fedora, RHEL)
Arch Linux

## How reproducible:

1. Use Arch Linux (up to date as of October 2025).
2. Ensure OpenSSL 3.6.0 is installed.
3. Install and configure nginx with a simple self-signed TLS certificate.
4. Launch any GnuTLS client such Epiphany, wget or aria2.
5. Open https://localhost/.

## Actual results:
Epiphany shows an SSL/TLS error 'Peer failed to perform TLS handshake: Error 
decoding the received TLS packet.'

In wget or aria2 similar error 'GnuTLS: Error decoding the received TLS packet'.

## Expected results:
Everything should work fine, regardless of the version of OpenSSL installed.
