Forge accepts a cert which has no subjectAltName and an empty subject

[Jennifer-first]

Forge accepts a cert which has no subjectAltName and an empty subject.
Section 4.1.2.6 Subject of RFC 5280 mentions that the subject name MAY be carried in the subject field and/or the subjectAltName extension.

To Reproduce：

const forge = require('node-forge');
const fs = require('fs');
const caPath = process.argv[2];
const certPath = process.argv[3];
const caCert = forge.pki.certificateFromPem(fs.readFileSync(caPath, 'utf8'));
const serverCert = forge.pki.certificateFromPem(fs.readFileSync(certPath, 'utf8'));
const caStore = forge.pki.createCaStore([caCert]);
console.log(forge.pki.verifyCertificateChain(caStore, [serverCert]));

node verify.js ca.pem seed.pem

Expected behavior：
Verification failed.
