Since we introduced PF4 together with the Drawer component to show the
config errors, we are not able to scroll the page by using the keyboard.
So far, no workaround really did the trick and every one came with
another drawback in different areas.
So we decided to ditch the Drawer component and use a Modal as
replacement. This should still serve the use case as we have "something
popping up when clicking on the bell icon", but this something doesn't
break the layout and/or the scrolling behaviour.
Additionally this change removes the "height: 100%" CSS rule on the root
element. In combination with the removed drawer this should restore the
scrolling behaviour via keyboard without introducing any further
drawbacks like wrong tabbing or focus behaviour.
For additional background information on this topic, please refer to the
changes [1], [2] and [3]. There is also a PF4 issue on Github available
[4].
