Some URL's causes library to "hang" #42

Parsing the URL "https://www.zalando.nl/nike-performance-trainingsbroek-blackcool-grey-n1241e0em-q11.html" causes the library to hang. It does not crash, but rather hangs for a very long time at 100% cpu-core consumption. Memory does not increase significantly.

Code to reproduce the problem:

const fetch = require('node-fetch');
const mf = require('microformat-node');

const fetchUrl = url => fetch(url)
    .then(res  => res.text())
    .then(html => mf.getAsync({html}));

fetchUrl('https://www.zalando.nl/nike-performance-trainingsbroek-blackcool-grey-n1241e0em-q11.html')

microformat-node version: 2.0.1
node version: v8.9.4 (also tested with v6.11.5 with same problem)

Could you please give me some pointers where to start looking in the code for a possible cause of this problem. Thanks!
