Ionic show keyboard gray bar issue

I tried to find a topic with this issue but I could not find it. We have an application with the following behavior when the keyboard is opened:
image

I tried to let the screen content aligned to the top (padding-top: 0px) but it happens anyway. When aligned to the top, the grey bar is smaller.

If I disable the scroll with cordova.plugins.Keyboard.disableScroll(false); the issue does not happen but the screen does not scroll so the field stay hidden behind the keyboard. Does anyone got this issue and managed to solve it?
