docs: Wait for a browser alert to appear, and switch to it. This should be usable
      as a drop-in replacement for driver.switch_to.alert when the alert box
      may not exist yet.
      @Params
      driver - the webdriver object (required)
      timeout - the time to wait for the alert in seconds
