Describe the bug
This configuration ends up running all tests with Firefox:
import { defineConfig } from 'vitest/config';
export default defineConfig({
test: {
browser: {
enabled: true,
provider: 'playwright',
instances: [
// Run all tests with Chromium, it's stable
{ browser: "chromium" },
// Firefox is flaky, run just one test
{ browser: "firefox", include: ["test/something-simple.test.ts"] },
],
},
},
});Reproduction

Happens on latest too, but due to #7913 reproducing the issue with 3.1.1 on Stackblitz.
