Behavior of Capybara's "have_no_content" when expected with `.to_not` and with `.to`

about to_not have_content:

  expect(page).to_not have_content("not on page")

it waits (Capybara's default waiting time), then it pass. Don't use it! 🚫

whereas to have_no_content:

  expect(page).to have_no_content("not on page")

Waits (same as with .to_not) but it passes as soon as "not on page" disappears from the page; use this one to wait for loading messages to disappear! ✅
