controlsList attribute doesn't reflect valid arguments

According to https://developers.google.com/web/updates/2017/03/chrome-58-media-updates#controlslist, controlsList attribute should reflect valid arguments.

In other words:

<video controls controlsList="nofullscreen foobar"></video>
<script>
var video = document.querySelector('video');
video.controlsList; // "nofullscreen" - "foobar" not present
</script>

It is not what happens in my JavaScript: "foobar" is present.
Is this WAI or a legit bug?

Note that video.controlsList.supports('foobar') returns false.

It's a feature request, but it should be fairly trivial.

Unfortunately, this is a bug in the documentation. DOMTokenList unfortunately, doesn't reflect validity this way and requires developers to use `supports()`. We probably don't want to have `controlsList` behaving differently.

Thanks! Here's the PR for updating documentation: https://github.com/google/WebFundamentals/pull/5163
