If gather the requirement correctly you can substitute utilizing
`console.assert()` shipped with the browser for a third-party library.

Not sure what the code or test is for playing `<video>` in a module or what
lead to the `Promise` rejection described when the `document` is reloaded?
Have run this code https://plnkr.co/edit/5bvp9xv0ciMYfVzG?p=preview (which
plays `<video>` in a JavaScript module) several times sequentially using
`autoplay` without a `Promise` rejection occurring.
