Large title bar on macOS Sonoma when using railwaycat/homebrew-emacsmacport and Doom Emacs

I confirm that...

• I have searched the issue tracker, documentation, FAQ, Discourse, and Google, in case this issue has already been reported/resolved.

• I have read "How to Debug Issues", and will use it to provide as much information about this issue as possible.

• The issue can be reproduced on the latest available commit of Doom.

• The issue can be reproduced on a stable release of Emacs, such as 27, 28, or 29. (Unstable versions end in .50, .60, or .9x)

Expected behavior

The expected behavior is to have a normal-sized title bar when opening Doom Emacs on macOS Sonoma. After upgrading to macOS Sonoma, something has changed, and it seems like a bug in Doom Emacs, based on the discussion here.

This is also discussed in railwaycat/homebrew-emacsmacport#362.

Current behavior

Opening Doom Emacs on macOS Sonoma leads to a title bar of this size:

However, running /Applications/Emacs.app/Contents/MacOS/Emacs -q --eval '(tool-bar-mode 0)' & leads to a title bar of this size:

Steps to reproduce

1. brew install emacs-mac --with-natural-title-bar
2. /Applications/Emacs.app/Contents/MacOS/Emacs -q to get large title bar
3. /Applications/Emacs.app/Contents/MacOS/Emacs -q --eval '(tool-bar-mode 0)' to get small/reasonable title bar
4. /Applications/Emacs.app/Contents/MacOS/Emacs to get large title bar with Doom configuration (regardless of whether config.el contains (tool-bar-mode 0))

Adding (add-hook 'doom-after-init-hook (lambda () (tool-bar-mode 1) (tool-bar-mode 0))) to config.el is a workaround as suggested by Dolerich in the linked Discourse post.

I think this was likely an upstream issue in emacs-mac. mituharu/emacs-mac@5f6c306 purports to have fixed it. I haven't had a chance to try out the fix myself yet, but I'll tentatively close this issue. Thanks and sorry for the noise!

In case someone else googles this:

The underlying issue is that the toolbar needs to be disabled before the window title bar style is changed. If you don't have the patched Emacs binary, you can toggle M-x tool-bar-mode on and off again interactively. That will be long after the startup sequence has set the window title and shrink the title bar.
