Title: BUGFIX: suppress error when scrolling at bottom of topic

Browse to a topic, then scroll all the way to the bottom of the page. Keep scrolling and watch the error console to see an "Uncaught TypeError: Cannot call method 'get' of null" error being thrown by topic_controller.

As far as I can tell the error doesn't actually break anything, so seems reasonable to just silence it and carry on.
