Steps to reproduce the problem:
1. Make sure you are using a windows tablet(you can see the on-screen keyboard icon in the taskbar)
2. Open a website (e.g. https://www.google.com)
3. Switch to another application, tab or your desktop
4. Switch back
5. Click(/touch) the input textfield right under the Google Logo
6. The on-screen keyboard doesn't show up
7. Click(/touch) the address bar
8. The on-screen keyboard will be automatically activated
9. Click(/touch) the input textfield again
10. Now the on-screen keyboard will be automatically activated

What is the expected behavior?
Every time I click an input textfield, the on-screen keyboard should be automatically activated.

What went wrong?
On-Screen Keyboard won't be automatically activated unless I click the address bar to "wake it up".

Did this work before? No
