Mouse-wheel-mode was enabled, if I disable it, the behaviour is the
same.

Emacs says:
<vertical-scroll-bar> <mouse-1> (translated from <mouse-1>) runs the
command scroll-bar-toolkit-scroll
   which is an interactive compiled Lisp function in `scroll-bar'.
It is bound to <vertical-scroll-bar> <mouse-1>.
(scroll-bar-toolkit-scroll EVENT)
Not documented.

Looks like it is the touchpad driver, not Emacs.
Thank you.
