Reproduction

When using test-utils v3.14 the myComponent.nuxt.spec.ts test pass:
https://stackblitz.com/edit/github-kucyss44?file=test%2FmyComponent.nuxt.spec.ts
When using test-utils v3.15 the myComponent.nuxt.spec.ts test fails:

Describe the bug

When using nuxt test-utils in v3.15, I can no longer catch errors thrown in the tested component using the errorCaptured option of mountSuspended:

let capturedError: string | null = null;

const component = await mountSuspended(MyComponent, {
  errorCaptured(err: unknown) {
    capturedError =
      typeof err === 'object' &&
      err !== null &&
      'message' in err &&
      typeof err.message === 'string'
        ? err.message
        : '';
    return false;
  },
});

expect(capturedError).toBe('This is an error');

It does work when using test-utils in v3.14. Trying to find alternatives I've also noticed that trying to catch errors using errorHandler also stopped working:

const component = await mountSuspended(MyComponent, {
  global: {
        config: {
          errorHandler(err: unknown) {
           // message displayed when using v3.14, not when using v3.15.
            console.log("error captured : ", err);
          },
        },
      }
});

It work when I replace await mountSuspended with mount from vue test-utils.
