It also breaks "back" IIRC. They expect you to use the "x" on the page to navigate back, not.. you know, the back button built into the browser. That and the scrolling are what got me to switch my iphone to DDG.
They must have actually had to do work to override the expected behaviour and break the user experience, which I just don't get.
I don't understand why Google has to break these well-established UI conventions.
Down with AMP!
