Headless mode: deprecation warning after upgrading

[fuhlig]

After the upgraded Puppeteer dependency with the latest 6.3.1 release, Puppeteer/Chrome throws the following deprecation warning:

docs:
https://developer.chrome.com/docs/chromium/new-headless?hl=en

While this is documented in the Backstop docs, it might be a better option is setting the headless mode to new by default to avoid deprecation warnings (and potential failures in future versions).

@fuhlig I agree, and know this is planned for a future release. "new" is not new so much anymore ¯_(ツ)_/¯

I'll look into submitting a PR for the change today.

Cheers mate

@fuhlig I just remembered to follow up! This can probably be closed — check out #1535 and backstop@latest (6.3.3).

There are some notes in the PR about Playwright to be aware of. We didn't think it was a good idea to default that runner to 'new' just yet.

Happy new year!

Awesome, thanks @dgrebb!
Will check it out next week

Have a happy new year!
