v5.3.5

A script nothing waits for no longer counts against how soon a page is ready.

Additions

• "load": "after" on a meta.scripts entry. An analytics tag listed
  in the HTML is fetched while the page is, even with async, and a
  page's speed is measured against everything it asked for before it first
  painted: Google's 174 KB tag added more than a second to a phone's
  Largest Contentful Paint on a page that was otherwise ready. A script
  marked "load": "after" has no tag in the HTML; the runtime asks for it
  once the page has loaded and drawn its first frame, with its
  meta.integrity hash when it has one. Its origin stays in the policy. A
  module, or a script whose globals .wf calls, cannot load after the
  page (E111).
