ClientHello TLS version 1.0 by default

[overflowingd]

Hi all. I'm trying utls and I found that there is no place in code to change an initial TLS version for ClientHello packet.
My Firefox sends TLSv1.3 by default. You can see a screenshot with captured TLS handshake of Firefox and some TLS server.
But utls sends ClientHello with TLSv1.0 constantly.

As I see in the code of the package, there is only one place where TLS version selection occurs:

func (c *Conn) pickTLSVersion(serverHello *serverHelloMsg) error {
	// ...
	c.vers = vers
	c.haveVers = true
	c.in.version = vers
	c.out.version = vers

	return nil
}

So, the package does not mimic the first thing that catches your eye when using Wireshark and I am interested in advice how to set the version when creating a connection.
Thanks.

Firefox version:

$ firefox -v
Mozilla Firefox 108.0.1

I apologize for wasting your time.
I found that this issue was reproducible when I used netcat as simple TCP server to handle connections from utls. I started a utls server on the other side instead of nc and the issue was gone away.
