bug#38179: 26.1; clone-buffer globally unsets locally void variable

My Emacs 26.1 does not seem to behave that way.
For example, evaluating the following form returns 2:

(with-temp-buffer
  (setq-default test 2)
  (makunbound (make-local-variable 'test))
  (default-value 'test))

Neither the info documentation nor the docstring of makunbound say how 
makunbound behaves for buffer-local variables, so my assumption was that 
like other Lisp forms it acts on the buffer-local value of local 
variables.

Best wishes,
