Platform: Chromebook Flip

Steps to reproduce the problem:
1. Open a site in Windowed mode on a Chromebook Flip in tablet mode
2. Follow a link on the site
3. Try to go back (without the keyboard)

What is the expected behavior?
I'd like a back button in the window bar in Windowed mode, as many websites rely on the back-button for navigation.

What went wrong?
I got stuck on a page below the one I started on because there was no way to navigate back without a back button.

Did this work before? N/A
