fixing the dynamic iframe's domain to solve the cross domain issue in IE when running in a page with a canonical domain defined.

// This is pure craziness, injecting an iframe in a page that has
// a fixed canonical domain will cause the dynamic iframe to fail
// to access the parent window.
// As a workaround, we can fix the domain in the dynamic iframe for IE.
