Fix navigating to comment flags through key bindings in the diff viewer.
Review Request #6493 — Created Oct. 23, 2014 and submitted
The support for navigating to comment flags using key bindings was
broken, due to looking up the wrong class. The class name has been
corrected, allowing navigation to work as expected.
Navigated between comment flags using key bindings.
