Describe the Bug
When tapping on an ion-input the view is scroll assisted to the very top of the screen, resulting in the input being located behind the ion-header and it fixes the in behind the ion-header.
A video demo of the bug in an app we're working on: https://youtu.be/BCSvphDrEzo

Steps to Reproduce
Steps to reproduce the behavior:

1. Create a standard page, using an ion-header and ion-content.
2. Create a number of ion-inputs, enough that they cover 75% of the screen.
3. Run the app on an iOS device with smaller screen size (i.e. iPhone 5s)
4. Click/focus on an input
5. Watch the keyboard appear
6. See that in some cases the input that is focused on appears behind the ion header when the keyboard appears

Related Code
I've added a gist of the markup to test: https://gist.github.com/pjhartin/06ac14785e12ea109f1183c69e57e2e5

Expected Behavior
I would expect the scroll assist when the keyboard appears to fix the input inside the viewport with a bit of margin/padding from the top, or at least not behind the header.

Additional Context
It would seem that from playing around with different amounts of content on the screen: if there is enough content for the keyboard to want to "push up" then the bug occurs.
