Ask HN: When did mobile Google start loading clicked links into an iFrame?

I noticed recently that when I click a Google search result in mobile Safari (latest/iOS10) that the page loads with a white box at the top saying whateverurl.com but the safari url box still says google.com. all of my long-press options are disable as the whole page has one giant overlay. i do not like at all that google is loading the pages I click inside of itself and overriding my browser controls. was there any news that they were starting to do this? any way to stop it?
