title: Soft Keyboard Disappearing when changing input
body: <p>Strange problem here which was caused by the most recent win 10 update 1709</p>
  
  <p>I have a uwp app that is installed on a tablet which has assigned access setup. So it is locked to this application in tablet mode. This was all fine until the last update which broke the keyboard.</p>
  
  <p>It pops up the first time, then when tapping the next input box it disappears. Then to get it to return you need to tap in the box again.</p>
  
  <p>I'm using the input scope on a few of them, and this seems to work intermittently too.</p>
  
  <p>Here's a video to demonstrate what I mean:

  <p>Any ideas? All nuget packages are up to date and it's targeting the latest version, I'm at a loss!</p>
