Steps to reproduce the problem:
1. flip the screen to put Chromebook in tablet mode
2. 
3. 

What is the expected behavior?
I should be able to bring up the on-screen keyboard or rotate the screen

What went wrong?
my chromebook will not switch to tablet mode. When the the screen is flipped I can still use the physical keyboard and the on-screen keyboard is no longer in the menu. Touch screen is still good but no keyboard and no screen rotate.

Did this work before? Yes 67.0.3396.99 / 67.0.3396.101
