Modal jumps to top on iPhone x - Ionic v4

Ionic Framework

Hi all,

I have problems with modals on iPhone X (Latest Ionic 4 release).
When I open a modal, the modal jumps to top. Only if I change the orientation, the modal jumps back to the right place.

Fixed it.
The problem was autofocus on the input component.

Somehow ionic modals doesn´t like autofocus.
