[Chore] Manifest fails to validate due to Specref issues

[mgiuca]

All of our manifest runs are failing to validate -- you can see by just loading up index.html in a browser. There are two specref issues:

  😱 ReSpec error: Couldn't match "document" to anything in the document or in any other document cited in this specification: dom, encoding, fetch, html, infra, screen-orientation, url, webidl. See how to cite to resolve the error at: 1.
  😱 ReSpec error: Couldn't match "list" to anything in the document or in any other document cited in this specification: dom, encoding, fetch, html, infra, screen-orientation, url, webidl. See how to cite to resolve the error at: 1.

I looked into both of these. The "document" one could have its tag removed, but it shouldn't need to. The "list" one is legitimate, it's trying to point at "list" in the Infra spec.

Searching for both of those terms in the given URL returns valid results. It just doesn't work in Respec. @marcoscaceres ?
