Huh, with or without comments, mark-defun always includes the empty
lines before the defun for me. I get the same behavior in rust-ts-mode.
This seems intentional, because this is at the end of the definition of
mark-defun:
(skip-chars-backward "[:space:]\n")
(unless (bobp)
(forward-line 1))
Are you using emacs-29 or emacs-30? Theo might have changed something on master.
