@playwright/test should be upgradeable to the latest version (currently ^1.39.0) if yarn-deduplicate is used on the lockfile, to merge the different versions being pulled in.

(note: in my testing, @microsoft/fast-ssr will require locking [email protected] after using yarn-deduplicate!)

When running all repo tests in streaming mode (yarn lerna run test --stream), there's a chance that runners will collide when trying to utilize port 8000. It's an intermittent failure which sometimes appears in parallel mode.

Closing this as it has many conflicts and has been out of date for some time, additionally this will be resolved in a future PR after we remove yarn and switch to npm.
