/**
* Bug 1713690 - Shim Google Interactive Media Ads ima3.js
*
* Many sites use ima3.js for ad bidding and placement, often in conjunction
* with Google Publisher Tags, Prebid.js and/or other scripts. This shim
* provides a stubbed-out version of the API which helps work around related
* site breakage, such as black bxoes where videos ought to be placed.
