Hmmm, works for me in an html file. See code below.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta name="generator" content="CoffeeCup HTML Editor (www.coffeecup.com)">
<meta name="dcterms.created" content="Sat, 15 Jul 2017 04:23:46 GMT">
<meta name="description" content="">
<meta name="keywords" content="">

<!--[if IE]>

Just save it as a html file (I used dropbox-test.html) and then point to it with your browser. Worked for me in Chrome. I did not try any other browsers.
