I'm testing an Ionic app with a Meteor backend, and when I went to change some colors of the theme today, I saw the warning for the first time.  My app doesn't use ads, but I think Chrome is wary of localhost because anything can run there.  I think this warning shouldn't show up since it's context sensitive.  By that, I mean not every instance of localhost shows ads.  It's not a real website.  I think this warning should never display for localhost.
