Prevent Apex setCookies prepend prefix 'apex_'

Question

Hi guys as may already know salesforce changed Debug logs for Site Guest User in winter 17. And I ran into a problem, I can't set the cookies from current page controller (Apex Controller), I get the cookies but with a prefix, in this case "apex_".

So my question, is there anyway to prevent Apex code prepend that prefix on my cookie name?

Here is the code I'm using. (I can't set document.cookie from JS, since current apex page content type is text/xml)

Apexpages.currentPage().setCookies(new Cookie[]{
    new Cookie('debug_logs', 'debug_logs', null, -1, false),
    new Cookie('domain', '.force.com', null, -1, false)
});
