Why are $ionicGesture events registered outside of the viewport

I have a view “A” with gestures attached, and a second view B.

If I go from view B to view A, then touch-coordinates are “outside” of the viewport/screen.

I have tested this now with B as multiple types of views, such as slide-box and ion-slides and the touch-coordinates in A are always outside of the screen when I go to A.

Why is this?
