The puppeteerLaunchOptions seems not working

[yixuanhou]

Describe the bug I suspect the puppeteerLaunchOptions is not working because I passed "new" to the headless option, and I still get the headless deprecation warning. I also tried passing false to it, and getting the same warning and there was no chrome instance launched.

To Reproduce

1. setting up .lighthouserc.js

   module.exports = {
   ci: {
   collect: {
     staticDistDir: "./build",
     puppeteerScript: "./puppeteer-script.js",
     puppeteerLaunchOptions: {
       headless: false,
       slowMo: 100,
     },
     settings: {
       disableStorageReset: true,
     },
     numberOfRuns: 1,
   },
   assert: {
     preset: "lighthouse:recommended",
   },
   },
   };

   And setting up puppeteer-script.js.

module.exports = async (browser, context) => {
  const page = await browser.newPage();

  await page.goto(context.url);

  await page.waitForSelector('input[type="email"]');

  await page.type('body input[type="email"]', user);
  console.log("email typed");
  await page.click('body input[type="submit"]');
  await page.type('body input[type="password"]', pwd);
  console.log("password typed");
  await page.click('body input[type="submit"]');

  await page.click('body input[type="submit"]');
};

Expected behavior I'm expecting when I set the headless to be false, after run lhci collect, a chrome browser gets launched so that I can debug the log in steps.

I am experiencing the same issue when passing { headless: "new" } to puppeteerLaunchOptions. The old headless deprecation warning still appears.

it works with cli option headful https://github.com/GoogleChrome/lighthouse-ci/blob/6914f5be825ea23e09edcd5cb46660b06dc38100/docs/configuration.md?plain=1#L206

it has preference over puppeteerLaunchOptions: https://github.com/GoogleChrome/lighthouse-ci/blob/6914f5be825ea23e09edcd5cb46660b06dc38100/packages/cli/src/collect/puppeteer-manager.js#L61-L68
