Context:

• Playwright Version: 0.11 and 0.12.1
• Operating System: Ubuntu 18 on Heroku

Chromium doesn’t work with Playwright on Heroku even with the recommended puppeteer build pack that worked with Playwright 0.9. Details and discussion in #634

To reproduce, use this repo and change the Playwright version: https://github.com/diervo/testing-heroku-playwright
