Comment (by afercia):

 The `itemSectionHeight()` calculation is wrong now, since the HTML/CSS has
 changed a bit. Though it's unrelated to the events stuff, would need some
 tweaking. Will leave the decision to committers of course :) Also, it
 would be better to get rid of the "magic numbers" there for at least a
 couple of reasons:
 - any future CSS change might change the accordion sections height
 breaking the calculation based on magic numbers
 - very long accordion section titles (custom post types, translations)
 might break in two lines and the accordion sections height wouldn't be
 "46" anymore
 The refreshed patch refactors `itemSectionHeight()` and includes a fix for
 IE 8 that doesn't support `window.innerHeight`.
