Popup identified as "doc" request when opened by iframe

[anewuser]

I've set these dynamic rules to block popups from this page:

no-popups: geektv.me true
no-popups: youwatch.org true

The popup is blocked if I open the iframe URL directly and click on the player: http://youwatch.org/embed-xlmfhm97etcg-850x450.html

However, if I click on the same player on the Geektv page, the ad popup isn't blocked because it's seen as a legit new document request: http://geektv.me/watch/14861

These two sites both have other ads, which I've blocked with other rules and filters. This issue is only about popups called by this function:

function lads() {
    window.open('http://ds1.vids.ma/KeclfbD2', 'velro', 'location=no,fullscreen=yes'); 
}

The popup URL may be different when you test it because they keep changing their ad hosts.
