[CSP2]Is there a directive dealing with the window.opener.location phishing concern?

hi,

I have read the CSP2 specs (http://www.w3.org/TR/CSP2/), and I found there
is no directive to block this situation:

if ( window.opener != null ) {
    window.opener.location.replace('http://www.evil.com');
}

Our website offer a web search service, we will open target link in a new
tab,
and some 3rd party website website use this script to redirect our page to
an evil page.

What can I do for this?
