title: Chromium/CefSharp touch events are not being fired
body: <p>I have a model view in wpf application that hosts url using chromium version 41.
  The url is html page that has two text inputs and each text input has a directive (angular 1.5) that binds the 'touchstart' event to each input.
  When I open the Url in chrome (with out the chromium wrapper) I can see that the touch events are working, and when I open the url under chromium the touch events are not being fired.</p>
  
  <p>Does anyone has seen this issue before? is it possible that it's related to the chromium version?</p>
