Properties added to the Document interface

What information was incorrect, unhelpful, or incomplete?

The "Page Visibility API" reference lists "unloaded" as one of the possible values of Document.visibilityState, but "unloaded" does not appear in the list on the "Document.visibilityState" reference.

What did you expect to see?

I expect "unloaded" to be listed on both or on neither.

The Page Visibility W3C Recommendation from 2013 lists

enum VisibilityState { "hidden", "visible", "prerender", "unloaded" };

but the current HTML Standard only lists

enum DocumentVisibilityState { "visible", "hidden" };

I assume removing "unloaded" is the right thing to do, but the deprecated value "prerender" is still listed on both pages and in the compatibility table so I figured I'd double-check first.

Per this W3C discussion from 2015, looks like "unloaded" was dropped from the spec before any implementation supported it.
