The X-UA-compatible header is not case sensitive; however, it must appear in the Web page's header (the HEAD section) before all other elements, except for the TITLE element and other META elements.
head-element returned by midpoint contains two script-elements before the meta http-equiv stuff which can cause incompatible page rendering.
Correct order can be achieved easily adding <wicket:header-items/> just after the meta tag in com\evolveum\midpoint\gui\api\page\PageBase.html
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1" />
please add this to master and 3.6.1
