title: Windows 10 Universal app won't show soft keyboard when focus on input areas
body: <p>I am building a Windows 10 Uiversal App Web App (Project Westminster). And I am testing it on my local device, which is a Surface Pro 3 running Windows 10. The app is running somoothly and as expected in desktop mode, but when I detach the keyboard and switch the device to tablet mode, the soft keyboard won't show up when I focus on the input areas, textareas etc. So I can't even login etc.</p>
  
  <p>However, if I run it on a Windows Phone emulator, the keyboard does show up when input got focused.</p>
  
  <p>Is there some configurations I need to set for my App so that the soft keyboard would show as expected on tablets? Thanks!</p>
