FFx and Webkit for Alpine + non sytem Chromium for perfs?

[jclaveau]

Goals

• Make Firefox work as a playwright browser in Alpine
• Make Webkit work as a playwright browser in Alpine

Monitoring

• Firefox
  • pw patch https://github.com/microsoft/playwright/blob/main/browser_patches/firefox/
  • https://github.com/GregorR/musl-firefox/
• Webkit
  • https://github.com/microsoft/playwright/tree/main/browser_patches/webkit
  • patches enabling musl? https://github.com/oven-sh/WebKit/blob/main/Dockerfile.musl
• Also a real musl based / patched version of Chromium may be faster (also avoid specific playwright.config.ts browser path) . Runtime cost: alpine loses ~10 s on the test step. Likely from apk chromium ↔ Playwright API negotiation differences vs the Playwright-bundled binary that ubuntu uses. Not catastrophic but real.
