Textbox moves up on Focus

When user focuses on the textbox, the screen moves up to a much larger height. This is in Ionic 3 (never faced such an issue in Ionic 1).

So to explain more, if i have a textbox (which is above the height of the keyboard), focussing on the textbox moves the screen upwards. This is not required since the keyboard has space available below the textbox. If i set the manifest to adjustPan, even in that case, the keyboard still moves up.

Incase of iOS, i have used disableScroll.

In both the cases, the user experience is quite bad, and this is one of the things that is reflecting negative on the Framework (I have been a big fan of this framework since the 1.0 days, and have done many projects in 1.x).

Any suggestions ?
