        <pre>Some times document.fonts.check() doesn't work. More specifically, it works, but always returns -- true. I do not know what is the reason, because it works fine in our staging env and fails on my local and production envs.

Repro:

1. Go to <a href="https://m.oumy.com/#/">https://m.oumy.com/#/</a>
2. Browser should load 3 Roboto fonts. None is loading.
3. Run in console: document.fonts.check('16px Roboto') and document.fonts.check('16px Zzz') -- both returns -- true.

4. Go to <a href="https://html5.oumy.com:8080/#/">https://html5.oumy.com:8080/#/</a>
5. See that 3 Roboto fonts are loaded.
6. Run in console: document.fonts.check('16px Roboto') and document.fonts.check('16px Zzz') -- both returns -- true.</pre>
