tap position option doesn't offset the position as requested

[ankur22]

Tested against: dbede12

Using position option on locator methods that has it doesn't offset the position as requested.

In the below code it works against localhost:8080, which is a test server that can be found here with instructions on how to run it locally: https://github.com/ankur22/testserver.

import { sleep } from 'k6';
import launcher from 'k6/x/browser';

export default function () {
  const browser = launcher.launch('chromium', {
    headless: false,
  });
  const context = browser.newContext();
  const page = context.newPage();
  const res = page.goto('http://localhost:8080/other');
  const l = page.locator('#cars-options');
  sleep(1);
  l.tap({
    position: {
      x: 0,
      y: 40
    }
  });

  sleep(10);
  browser.close();
}

In the test above, it should select the third option in the select menu, but it always selects the first option.
