Unfortunately this logic is wrong, it fails for the standard prebid case (always evaluates to true when not in an iframe).

Yes you are correct, this breaks my test page; we should have tested that.

I think the problem here is we need to check a passed in window param, which we don't have. I think we have to change the renderAd API to accept the window instead of doc :(

Hmm; I would hate to break backwards compatibility. Suren and I will brainstorm some techniques to see if we can come up with a backwards compatible solution that still solves this problem, and if so we'll update the pull-request. Thanks!

@mkendall07 updated this to be more specific for our case so it doesn't break the general Prebid.js case. Also updated |

@prebid/core can we get another review on this to see if it's good to go? We'd like to merge this sooner than later. Thanks! |

Type of change
Description of change
For PostBid implementations, the secondary iframe ('postbid_if') where the ad is inserted into can cause view-ability metrics to drop. This enhancement allows the passing of the current document to the renderAd provided that prebid is loaded inside an iframe.
