Why does this "Slow network detected..." log appear in Chrome?
<p>I noticed this <code>info log</code> began to appear in Google Chrome Dev (Version 55.0.2883.18 dev) and I can't imagine why.</p>

<blockquote>
  <p>Slow network is detected. Fallback font will be used while loading: <a href="http://font-path.extension" rel="noreferrer">http://font-path.extension</a>`</p>
</blockquote>

<p>It appears on all websites that use <code>font-face</code>, even on local pages and Chrome extensions.</p>
