Navigation promise placement is wonky sometimes

[tnolet]

examples are:

1. it comes after the navigation...

(async () => {
  const browser = await puppeteer.launch()
  const page = await browser.newPage()
  
  await page.setViewport({ width: 1280, height: 694 })
  
  await page.goto('https://someurl')
  
  await page.waitForSelector('.vertical-center > .row > .col-md-offset-4 > form > .btn-primary')
  await page.click('.vertical-center > .row > .col-md-offset-4 > form > .btn-primary')
  
  const navigationPromise = page.waitForNavigation()
  await navigationPromise
  
  await browser.close()
})()

2. There are many duplicates after one navigation. No example yet.
