  <C-wheel-up> at that spot runs the command mouse-wheel-text-scale
  (found in global-map), which is an interactive compiled Lisp function
  in ‘mwheel.el’.

  It is bound to <C-wheel-down>, <C-wheel-up>.

  (mouse-wheel-text-scale EVENT)

  Increase or decrease the height of the default face according to the EVENT.

It is documented to increase/decrease the size of _text_ of the
default face.  It isn't documented to "zoom", which is a much more
general action/effect.
