Were animations between tabs removed/broken?

I was able to create a CodePen where you get a animation between tabs in version 0.9.27 of Ionic. Once I upgrade it tot 1.0.0 the animations are gone. I can’t find anything about it in the docs, nor in the changelogs. Was this removed or did the markup change?

Animations working on 0.9.27

Animation broken on 1.0.0
