Were you able to solve this with $ionicScrollDelegate.resize()?
I'm having the same issue except that my list that expands is inside a directive and so I think I need to broadcast the event to the parent scope which has access to ion-content which $ionicScrollDelegate.resize() can be called on. Tried this but despite the resize being called, my view still jumps back until a second or third try scrolling all the way down, then it finally resizes
