[MediaQuery] Foundation.MediaQuery.current return undefined in Firefox

[geosigno]

Since the 6.5.0.rc-4 (at least); it seems the media query are not working anymore on Firefox.

import { Foundation } from 'foundation-sites/js/foundation.core';
import { MediaQuery } from 'foundation-sites/js/foundation.util.mediaQuery';

Foundation.MediaQuery = MediaQuery;

Foundation.MediaQuery._init();

console.log(Foundation.MediaQuery.current);

On chrome it print 'xxxlarge', but in firefox it prints 'undefined'. I am pretty sure it is the same on IE.

Can you provide a working codepen so we can reproduce it against the latest RC?

Sorry mistake on me. My code was executing too soon, I guess the meta with media query was not loaded yet, so query was empty.
