CORS Access-Control-Allow-Headers issue with addresspicker GoogleMaps API

I keep getting this error,

XMLHttpRequest cannot load http://ift.tt/1SzC0Sp. Request header field X-Pusher-Socket is not allowed by Access-Control-Allow-Headers in preflight response.

And If I do enable the CORS adon in Chrome, it just works fine. Happening on Production, Staging and development.

Also, the page having this broken has ember in it, any other page just works fine.
