[BUG] chromium --remote-debugging-port arg does not work

Context:

• Playwright Version: v1.1.1
• Operating System: Mac
• Node version: v12.16.3
• Browser: Chromium

Code Snippet

const http = require("http");

const { chromium } = require("playwright");

(async () => {
  const browser = await chromium.launch({
    args: ["--remote-debugging-port=9999"],
    headless: false,
  });

  const page = await browser.newPage();

  http.get("http://localhost:9999");
})();

Describe the bug

This script throws Error: connect ECONNREFUSED 127.0.0.1:9999.

I see there is a test that it does not throw an error, but not one for connecting to the port. Is this argument not supported?

I just saw that when I was investigating the source code to make a PR for this. That works, thanks!

@jperl To aid VSCODE, you can pass PLAYWRIGHT_CHROMIUM_DEBUG_PORT=9999 env variable. It was added awhile ago specifically for this purpose!

Does it help?
