 While trying to hook into someone clicking the expand/collapse arrow in
 the nav menu UI, I realized that the existing Javascript is using `return
 false;` to abort the hyperlink click from going through.

 [http://fuelyourcoding.com/jquery-events-stop-misusing-return-false/ This
 is bad and incorrect.]

 We should be using `object.preventDefault()` instead so that other bound
 functions aren't aborted.
