Forget this question please.  I can now reproduce with master, too.

But: This is only reproducible when I build Emacs with native
compilation enabled.  Then I get this backtrace with your recipe:

| Debugger entered--Lisp error: (wrong-type-argument integer-or-marker-p nil)
|   forward-paragraph(1)
|   fill-forward-paragraph(1)
|   fill-region(11 528 left t)
|   easy-mmode--mode-docstring("MWE mode" "Mwe mode" mwe-mode-map mwe-mode nil)
|   #f(compiled-function (arg1 arg2 &rest rest) "Define a new minor mode MODE....
|   elisp--eval-last-sexp(nil)

When I load the source of paragraphs.el (where `forward-paragraph' is
defined) the problem goes away.

Maybe Andrea can help?  Just CC'd - I don't know how to continue here.

Thx,

Michael.
