Under Node, openssl.js always uses the real filesystem instead of the provided one

[CyberShadow]

const openssl = require('./openssl.js/dist/openssl.cjs');
const path = require('path');
const fs = require('fs');

let fakeFs = {
  existsSync : () => true
};

var openSSL = new openssl.OpenSSL({ fs : fakeFs });

(async function () {
  // Fails with "No such file or directory", but fakeFs.openSync is never called
  await openSSL.runCommand('base64 -d -in /file.txt');

  fs.writeFileSync('file.txt', 'dGVzdAo=\n');
  // Prints the (base64-decoded) contents of the real file.txt
  await openSSL.runCommand('base64 -d -in ' + fs.realpathSync('file.txt'));
})();

This is due to issues with the wasi wrapper and some of the syscalls OpenSSL uses. We are looking into the issue.
