The workflow installs Chromium. The suite runs no other browser. `wp-scripts test-playwright` then runs `playwright install` again, which downloads Firefox and WebKit and warns about libraries they need. Set PLAYWRIGHT_SKIP_BROWSER_DOWNLOAD on the test step when the workflow installs the browsers.
On ubuntu-24.04 the runner image already provides every shared library Chromium needs. The apt step reports each one as already the newest version. `--with-deps` then installs 9 font packages, 21.1 MB, and adds about 27 seconds to every E2E job. Those fonts cover CJK, Thai, and Cyrillic. No spec in tests/e2e uses those scripts, the workflow installs only de_DE, and no spec asserts on a screenshot. The performance workflow keeps `--with-deps`. Its metrics feed a trend, and a font change could shift them.

`playwright install chromium` reads plainly on its own. The reason for leaving out `--with-deps` belongs in the ticket, not in the workflow.

The E2E workflow does two pieces of Playwright setup that nothing uses.
A second browser install.
wp-scripts test-playwrightrunsnpx playwright installwith no browser argument, which installs Chromium, Firefox, and WebKit. An earlier step already installed Chromium, so every job downloads Firefox and WebKit and never opens them. SettingPLAYWRIGHT_SKIP_BROWSER_DOWNLOADon theRun E2E testsstep makeswp-scriptsskip it.--with-deps. Onubuntu-24.04, every shared library Chromium needs reportsalready the newest version. The flag installs nine font packages instead, covering CJK, Thai, Cyrillic, and the X core fonts. No spec intests/e2euses those scripts, the workflow installs onlyde_DE, and no spec asserts on a screenshot.Before, on trunk run 33649288756:
After, on run 33661004598 for this branch: none of those lines appear, Chromium and the headless shell still install, and both jobs pass 27 tests, the same count as the trunk run. Each job finished about a minute sooner. A single pair of runs makes that figure noisy; the removed work accounts for roughly 36 seconds of it.
