This ignores data from <link rel=prerender> that is coming from the page
currently being offlined. These prerenders are being removed, but we still can
potentially issue a NoStatePrefetch from this entry point until we factor it out
of Prerender code.

This accounting is OK to me, just wanted you to confirm that it is what you
want.
