Run them in headless [vitest browser mode](https://vitest.dev/guide/browser/) in chromium and firefox. Similar UX than current tests, it's about 5 times as slow (goes from 1s to 5s on my machine), but definitely worth it as it removes all happy-dom problems. --------- Signed-off-by: silverwind <me@silverwind.io>
