I encountered this bug from Emacs mac port
bitbucket.org/mituharu/emacs-mac/src/work/ 28.0.92 to make sure it's
not only on that port, I download Emacs from
emacsformacosx.com and
reproduced the bug. I found that emacs -Q is not available in Terminal so I tested
it with no init files.
This is the first time I reported a bug to Emacs, please forgive me for any
inappropriate thing.
