title: How can I detect IE10 from JS when browser mode is IE9?
body: <p>I need to detect with just plain javascript (no frameworks) when the browser is IE10 despite the browser mode setting.</p>
  
  <p>Some comments:
  - I do need to detect the browser, it isn't an option to detect just features since the purpose is mitigating a browser bug.
  - I have tried the common ways (like UA string or feature detection) with no success, when I switch browser mode to IE9 every aspect that could suggest being in IE10 just vanishes.</p>
