28.0.50; Function with more than one key gives "wrong number of arguments" error |

Here is something that could be a bug, I cannot know at this moment, as
I am researching yet if I can use &key with Emacs's `defun':
(defun tmp-function-1 (text html &key one)
"This one works fine"
(message one))
(tmp-function-1 "text" "<html>" :one "Hello")
(defun tmp-function-2 (text html &key one two)
"This one does not work, wrong number of arguments"
(message one))
(tmp-function-1 "text" "<html>" :one "Hello" :two "But not alright")
Evaluating the last function does not work, it gives the error:
Debugger entered--Lisp error: (wrong-number-of-arguments ((t) (text html &key
one) "This one works fine" (message one)) 6)
tmp-function-1("text" "<html>" :one "Hello" :two "But not alright")
eval((tmp-function-1 "text" "<html>" :one "Hello" :two "But not alright") nil)
elisp--eval-last-sexp(nil)
eval-last-sexp(nil)
funcall-interactively(eval-last-sexp nil)
call-interactively(eval-last-sexp nil nil)
command-execute(eval-last-sexp)
I have tried searching the manual for Emacs Lisp for anything related to
`&key' and I cannot find any references, in my opinion the description
of `defun' in the Emacs Lisp manual is not satisfactorily.
