Reproduction

Similar to here.
Ist about the nuxt environment.
I changed it from happy-dom to nuxt. Since then it is not coverging pages.
The Stackoverflow user had a much simpler set up without projects.

import {
  defineVitestConfig,
  defineVitestProject,
} from "@nuxt/test-utils/config";
import vue from "@vitejs/plugin-vue";
import AutoImport from "unplugin-auto-import/vite";
import { configDefaults, defineConfig } from "vitest/config";

// 1️⃣ Nuxt-specific setup via defineVitestConfig
const nuxtConfig = defineVitestConfig({
  test: {
    environment: "nuxt",
    globals: true,
  },
});

// 2️⃣ Full Vitest config using core defineConfig
export default defineConfig({
  ...nuxtConfig,
  test: {
    coverage: {
      provider: "v8",
      reporter: ["text", "json", "html"],
      reportsDirectory: "./tests/coverage",
      exclude: [
        ...(configDefaults.coverage?.exclude ?? []),
        "**/*.cy.ts",
        "**/*.cy.tsx",
        "**/cypress/**",
        "nuxt.config.ts",
        "scripts/**",
      ],
      thresholds: { statements: 90, branches: 90, functions: 0, lines: 90 },
    },

    projects: [
      {
        test: {
          name: "Server (Node Environment)",
          include: ["tests/server/**/*.{test,spec}.ts"],
          globals: true,
          environment: "node",
        },
        plugins: [vue(), AutoImport({ imports: ["vue"], dts: true })],
      },
      await defineVitestProject({
        test: {
          name: "Happy NUXT Environment",
          include: [
            "tests/pages/**/*.{test,spec}.ts",
            "tests/components/**/*.{test,spec}.ts",
            "tests/composables/**/*.{test,spec}.ts",
            "tests/utils/**/*.{test,spec}.ts",
            "tests/plugins/**/*.{test,spec}.ts",
            "tests/layouts/**/*.{test,spec}.ts",
            "tests/directives/**/*.{test,spec}.ts",
            "tests/mixins/**/*.{test,spec}.ts",
            "tests/app.test.ts",
            "Tests/error.test.ts",
          ],
          exclude: ["tests/server/*.{test,spec}.ts"],
          globals: true,
          environment: "nuxt",
          setupFiles: ["./tests/setup.ts"],
        },
      }),
    ],
  },
});

Describe the bug

nuxt environment doesn't create coverage for pages

Additional context

I tried additionally and explicitly adding pages to includes. But it doesn't work.
Please, tag me, if it requires to be opened up in a different repository, such as vitest.

Logs

Start with the Vitest configuration shown in the issue, especially the coverage settings and the Nuxt project defined with defineVitestProject. Run the tests included under tests/pages and compare their results with the generated coverage reports. Done means Nuxt page files are represented in coverage without breaking the existing server and component test projects.
