[🐛 Bug]: JS- ECONNREFUSED when using two WebDrivers and .quit()ing one

What happened?

So I have two built web drivers. On each I navigate to a specific site with a .get(). Then on one of them I use .quit() to close it. Then i try to use the second driver that is still open and try to navigate to a different site(really just do anything with the driver). Upon trying to use the second driver that should still be opened and using any API call, I get this ECONNREFUSED error. It appears that for some reason calling .quit() on the first driver also destroys the communication between selenium and the second driver.

I have pinpointed that this bug was introduced in Selenium 4.0.0-alpha.5 and has persisted until the latest version of selenium(4.1.1). Trying to do this should work as it works with versions prior to 4.0.0-alpha.5.

This same behavior also occurs MsEdgeDriver. Which leads me to believe this is a problem with selenium and not chromedriver. Also worth noting that this does not occur when using geckodriver.

How can we reproduce the issue?

const { exec, spawn } = require('child_process');
const webdriver = require('selenium-webdriver');
const BROWSER_NAME = webdriver.Browser.CHROME;
const chrome = require('selenium-webdriver/chrome');

async function startChromedriver() {
    const chromedriverExecutable = process.platform === 'win32' ? './chromedriver.exe' : './chromedriver';
    const child = spawn(chromedriverExecutable, { detached: true, stdio: 'ignore' });
    child.unref();
}


async function stopChromedriver() {
    return new Promise((resolve, reject) => {
      const cmd = process.platform === 'win32' ? 'taskkill /F /IM chromedriver.exe' : 'killall chromedriver';
      try {
        exec(cmd, (error, stdout, stderr) => {
          if (error) {
            resolve(false);
          }
          resolve(stdout);
        });
      } catch (error) {
        resolve(false);
      }
    });
}

async function getDriver() {
  const options = new chrome.Options();

  return new webdriver.Builder()
  .forBrowser(BROWSER_NAME)
  .withCapabilities(webdriver.Capabilities.chrome())
  .setChromeOptions(options).build();
}

async function doStuff(){

    await startChromedriver();

    const firstDriver = await getDriver();
    firstDriver.get('https://google.com')

    const secondDriver = await getDriver();
    await secondDriver.get('https://youtube.com')

    await firstDriver.quit();

    await secondDriver.get('https://reddit.com'); // <-- ECONNREFUSED here
    await secondDriver.quit();
}

doStuff();
