-/**
- * Tests logic in the ReaderModeManager.

[Theresa, 2017/05/11 22:31:18]

This class was mostly testing overlay panel behavior?

[mdjones, 2017/05/12 19:13:10]

Exclusively. It was testing all the interactions that infobars just get for
free. We don't need to have any custom handling any more, so this class is
unneeded.
