TLS maxVersion not working

[ghost]

• Version: v10.15.0
• Platform: Windows 10 Home v10.0.14393 x64
• Subsystem: TLS

When using TLS.connect() the options are passed to TLS.createSecureContext().
TLS.createSecureContext() can take a maxVersion argument which specifies the maximum TLS version to allow, however this doesn't work.
The snippet below demonstrates that when you pass a maxVersion value of TLSv1 the connection succeeds even though the domain personal.natwest.com does not support TLS 1.0

const TLS = require("tls");

let options = {
    port: 443,
    host: "personal.natwest.com",
    maxVersion: "TLSv1"
};

let socket = TLS.connect(options, () => {
    console.log("Success");
    socket.destroy();
}).on("error", (err) => {
    console.log("Error");
    socket.destroy();
});

minVersion and maxVersion were added in 11.4.0. So they will have no effect in 10.15.0.

Of course, sorry completely missed that

minVersion and maxVersion are being added to 10.x in #24979 but that version won't be out until March, if all goes according to plan.
