How to prevent Ember.js 1.0.0 from removing URL parameters?

I use Ember 1.0.0 and i can not update to new versions now. I need a solution for Ember 1.0.0.

For example Google Adwords needs to pass custom parameters to visited website so Analytics can measure the traffic. I need to have it.

So for example URL is: http://ift.tt/29aC0nI

But after website loads Ember strips custom parameter. How to prevent it without updating Ember.js?

( In case Ember does not strip custom parameters please write, because if so, some JS code on my website does this. Thanks! )
