AFAIU, that's how macOS apps behave in terminal and in GUI mode.
Emacs just reflects the truth.

But I'll let macOS experts chime in.

It seems like that. My only reason to fire up Emacs from the Terminal was
to pass command-line arguments like --debug-init but since I use Spacemacs
this is builtin via the restart-emacs package. However, I didn't dig in
much to see how command-line arguments are passed through GUI restart.

Does anyone else have an opinion here?  I'm hardly an expert on macOS,
but it seems to me that Eli is right.

Mine doesn’t do that. Are you using some sort of iCloud sync thing?
What do you get if you just type pwd in the terminal?

It’s worth noting that the environment is different when you run an
app from the terminal versus when you run it from the GUI. All sorts
of things are different.

More information was requested, but none was given within 27 weeks, so
I'm closing this bug.  If this is still an issue, please reply to this
email (use "Reply to all" in your email client) and we can reopen the
bug report.
