Cannot center input content

With Ionic v4, we are seeing many issues with centering content.
No matter what I try, grid, flex, height 100%. The keyboard does something funcky with IonicContent when focusing the input. Here is a video:

The following fixes it on both desktop and mobile.

React =

.colCenter {
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: center;

.fixedMiddle {
    position: fixed;
    top: 0;
    bottom: 0;
