instantsearch.widgets.searchBox does not apply custom cssClasses to search input

[cmalpeli]

Implementation:

search.addWidget(
    instantsearch.widgets.searchBox({
      container: '#search-box',
      placeholder: 'Search profiles...',
      wrapInput: true,
      cssClasses: {
         input: 'form-control search-input'
      }
    })
  );

Chrome (Mac) Output:
<input autocapitalize="off" autocomplete="off" autocorrect="off" placeholder="Search profiles..." role="textbox" spellcheck="false" type="text" value="" class="ais-search-box--input form-control search-input">

IE 11 Windows 10 PC Output:
<input class="ais-search-box--input" role="textbox" spellcheck="false" type="text" placeholder="Search profiles..." value="" autocapitalize="off" autocomplete="off" autocorrect="off">

You can see this in action on pythonjobs.com/profiles

Thanks!
