I’ve just had a fiddle with an IE11 browser I’ve got laying around, and if you hit F12, click on the “Console” tab, you get what you need. If I type:
window.ie
it prints
undefined
If I then type
window.history
it prints
[object History] (other gibberish)
If I then type
window.history.pushState
it prints
function pushState() { [native code] }
If I type
navigator.userAgent.indexOf("Android")
it prints
-1
If you get results different to these, please post a full screenshot of the results you do get. If you get the same results, but IE11 is still causing you problems, then please provide a publicly-accessible URL (the site you linked to earlier is buried behind mandatory SSO) that exhibits the problem.
