I hear no requests to keep the prefixed version. Does any port want it? If not, I \
will simply unprefix without preserving the prefixed behavior.

In unprefixing, there will be a minor API change. We have a "preview" state that, \
theoretically, can be returned from document.visibilityState (but I don't think we \
ever did).

That was replaced in 2011 by a "unloaded" state, which the document passes into when \
it's being unloaded. I will add the string, but support for this in the spec is \
optional; I don't intend to hook this up at this time. See \
<https://bugs.webkit.org/show_bug.cgi?id=116645>

The unprefixing bug is <https://bugs.webkit.org/show_bug.cgi?id=102340>.
