`vscode-test-cli` not excluding files from coverage report

I have the following configuration file:

/** @type {import('@vscode/test-cli').IConfigurationWithGlobalOptions} */
export default defineConfig({
  /** @type {import('@vscode/test-cli').TestConfiguration[]} */
  tests: [
    {
      files: [
        `__tests__/__integration__/out/__tests__/__integration__/**/*.test.js`,
      ],
      version: "stable",
      extensionDevelopmentPath: __dirname,
      workspaceFolder: `${__dirname}/__tests__/__integration__/resources`,
      srcDir: "./src",
    },
  ],
  /** @type {import('@vscode/test-cli').ICoverageConfiguration} */
  coverage: {
    includeAll: true,
    reporter: ["lcov", "text-summary"],
    output: `${__dirname}/__tests__/__results__/integration`,
    exclude: ["**/node_modules/**"],
  },
});

And I am unable to generate a coverage report that excludes my node_modules event though I specifically mention to exclude those in coverage.exclude any idea if i'm missing something in my configuration?
