I think setting x-ua-compatible ie=edge doesn't mean use the Edge EdgeHTML engine - it means enabling "Edge mode" in IE, which means "the latest available version of IE" and you end up with IE10 or IE11.
EdgeHTML can be embedded, but only using the WinRT API, not the ActiveX WebBrowser control.
Welcome to the web, where browsers are named after existing browser concepts in as confusing a way as they can come up with. “You know how browsers have chrome around the web content, and how that’s the accepted term of art? Let’s call our browser Chrome!” “You know how we can tell IE to run in edge mode? Let’s call our replacement browser, which IE compatibility mode won’t be able to use, Edge!”
