What version of React are you using? (can be found by running npm list react) 16.5.2

What browser are you using? Chrome

Describe the Problem

Expected behavior: [What you expect to happen] Full screen button toggles its appearance when clicked.

Actual behavior: [What actually happens] Full screen button does not toggle back after full screen is deactivated using the button. It resets on slide change, however.

Spotted by @ollie-nye when we were checking out a template I'm working on just now. I used spectacle-boilerplate, but I don't think the issue is specific to that.

Hey @boardfish could you please put together a small codepen or gif that demonstrates the issue you're running into? We haven't been able to reproduce on our end. Thanks!
