Ionic 2 screen height dynamically changes while showing keyboard on device

[fedorinoGore]

Short description of the problem:

I accidentally discovered that screen vertical size changes after I'm clicking an input field in a from and device keyboard appears. After I closing keyboard - the height is still bigger than needed (and bigger than it was before) and I could scroll in vertical direction far beyond the visible area.

What behavior are you expecting?

It looks like that framework adds some height to the to make sure that keyboard will not overflow UI controls. But after hiding keyboard it should return to normal height, I believe...

Steps to reproduce:

1. Create a form inside a
2. Add some fileds
3. Run on the device and tap on input field.
4. Tap somewhere else to change focus
5. Scroll in vertical direction to see that screen size dramatically changed...
