initWithBrowser: is marked as "designated initializer" (
https://developer.apple.com/library/ios/documentation/general/conceptual/devp...
"The designated initializer of a subclass must invoke the designated initializer
of its superclass by sending a message to super"), so this comment contradicts
that.

Done.
