https://github.com/eduter/playwright-firefox-docker

Describe the bug

It starts the container and tries to run the example test on Firefox, but then just hangs forever like this:

playwright-ff  | > playwright test example --project=firefox
playwright-ff  |
playwright-ff  | 
playwright-ff  | Running 1 test using 1 worker
playwright-ff  |
                 [1/1] [firefox] › example.spec.ts:3:1 › homepage has Playwright
