🟢 Playwright bot here — I checked the CI failure, and it is a confirmed pre-existing flake

playwright.spec.ts:303 › should respect headless in modifiers that run before tests has failed on unrelated PRs and passed on rerun. This PR only reverts a list-reporter output option, so it does not reach browser launch or headless configuration.

Details

Pre-existing flake / infra

• [playwright-test] › playwright.spec.ts:303 › should respect headless in modifiers that run before tests — the nested test launched headed Chromium without an available X server (Missing X server or $DISPLAY). The same test failed on unrelated #42096 and #41460, then cleared on #41460's rerun. The changes here are limited to the list reporter and its docs, types, and test, with no changes to the fixture or launch paths exercised by this test.
