Isn't that changing the goalpost a little bit? I don't think anyone ever called Safari the new IE because of market dominance.
Personally, I compare it to IE because of how weird it can be. Does anyone else remember the time they broke file upload[1], even though those issues were found in beta[2]? Or about the time they changed meta viewport[3]?
Edit: Oh, the last link also remind me of the window.location change that utterly broke Angular/Ionic[4].
