Metrics aren't being associated with a group

[ankur22]

Brief summary

While investigating a community support question, I ran into an issue where I noticed that metrics weren't being grouped into groups.

Script:

import { chromium } from 'k6/x/browser';
import { group } from "k6";

export const options = {
  thresholds: {
    'browser_dom_content_loaded{group:::home}': ['p(95)<500'],
    'browser_dom_content_loaded{group:::coinFlip}': ['p(95)<500'],
  },
};

export default async function () {
  const browser = chromium.launch({headless: false});
  const context = browser.newContext();
  const page = context.newPage();
  const page2 = context.newPage();

  try {
    await group('home', async function () {
      await page.goto('https://test.k6.io/')
    })

    await group('coinFlip', async function () {
      await page2.goto('https://test.k6.io/flip_coin.php')
    })
  } finally {
    page.close();
    browser.close();
  }
}

Output:

     browser_dom_content_loaded.......: avg=71.42ms  min=47µs     med=51µs     max=214.18ms p(90)=171.36ms p(95)=192.77ms
     ✓ { group:::coinFlip }...........: avg=0s       min=0s       med=0s       max=0s       p(90)=0s       p(95)=0s
     ✓ { group:::home }...............: avg=0s       min=0s       med=0s       max=0s       p(90)=0s       p(95)=0s
