You have 3 comments in this thread stating that this wasn't reviewed correctly. It was, you're just looking at the wrong link in their bugtracker: http://trac.webkit.org/changeset/194667 "Reviewed by Tim Horton."
You are the one who is mistaken, not me. I never said the revert wasn't reviewed, and neither did Simon Fraser. What he said was the commit that caused the viewport bug that made its way into iOS 9.2 wasn't reviewed.

That clear enough for you now?
