<pre>On iOS devices seen on build Chrome 44 and current build of Safari. (Was OK in Chrome 40)
A header element with position:fixed;z-index:1000;top:0 becomes unfixed and lands over content during focus on element such as input element. On blur event, position:fixed is restored
This is hard to demo as position:fixed seems broken in iframe, so codepens with position:fixed seems not to be fixed in ANY state:

My work-around solution is to script a change in layout from position:fixed to position:absolute during .focus and return to position:fixed with .blur.</pre>
