Forge accept a certificate with version 1 and extension fields #1145

I have a certificate chain [rootCA,intermediate certificate,leaf certificate], where the leaf certificate has an extended field with a version number of 1. This leaf certificate violates RFC5280 Section 4.1.2.1: "When using extended fields (as expected in this specification), the version number must be 3 (currently 2)." However, this certificate chain still passes Forge's certificate verification.

To Reproduce：

const { pki } = require('node-forge');
const { readFileSync } = require('fs');
const [, , caPath, certPath] = process.argv;
const caStore = pki.createCaStore([pki.certificateFromPem(readFileSync(caPath, 'utf8'))]);
const serverCert = pki.certificateFromPem(readFileSync(certPath, 'utf8'));
console.log(pki.verifyCertificateChain(caStore, [serverCert]));

node verify.js ca.pem seed.pem

Expected behavior：
Verification failed.
