I encountered this on macOS today. Reproducer with an installed Emacs 
(which is the Emacs.app on macOS):

  ~/Desktop/Emacs.app/Contents/MacOS/Emacs -q

In *scratch*, eval

 (global-set-key [f4] #'kill-current-buffer)
 (documentation 'rectangle-mark-mode)

Then C-h k <f4> and observe that it has been redefined.

A backtrace how this happens with which-key is at then end. In short,
which-key calls 'documentation' which loads lisp/loaddefs which
evaluates the global-set-keys loaddefs.el contains.

I have no idea how to fix this.
