Doom Emacs seems to break the "new tab" button on Emacs Macport

### I confirm that...

- [X] I have searched the [issue tracker](https://github.com/doomemacs/doomemacs/issues), [documentation](https://docs.doomemacs.org), [FAQ](https://docs.doomemacs.org/-/faq), [Discourse](https://discourse.doomemacs.org), and [Google](https://google.com), in case this issue has already been reported/resolved.

- [X] I have read "[How to Debug Issues](https://doomemacs.org/d/how2debug)", and will use it to provide as much information about this issue as possible.

- [X] The issue can be reproduced on the **latest** available commit of Doom.

- [X] The issue can be reproduced on a stable release of Emacs, such as 27 or 28. *(Doom does not support development builds like 29+ or any version ending in .50 or .9x)*

### Expected behavior

When I click on the `+` button (see top right corner) of the tab bar, it should open a new tab.

### Current behavior

Currently, clocking on the `+` button of the tab bar opens a new frame, instead of a new tab.

### Steps to reproduce

1. Use the Emacs Macport (https://bitbucket.org/mituharu/emacs-mac)
2. Hit `C-` to show the tab bar
3. Click the `+` button on the tab bar
