Sage is incompatible with symbolic links : Unrecognized file extension

Version

10.6.0

What did you expect to happen?

I wanted to develop a theme using Sage, Acorn and symbolic links (ln -s PATH TARGET) to link the actual theme directory located in a different folder to the wp-content/themes directory (I'm not using bedrock, but i think this also applies there).

The theme should successfully load but it did not.

I resolved the issue by switching from a symbolic link to copying the theme inside of wp-content/themes but this is not a real fix and degrades the development experience and possibility to keep the theme's source separate of wordpress (e.g. no easy re-use on multiple wordpress installs)

What actually happens?

The theme did not load successfully and threw error:

InvalidArgumentException:
Unrecognized extension in file: /home/admin/htdocs/wpress.

Steps to reproduce

Break:

Create a new Sage project in some other location than the WordPress install
Install Acorn, build assets...
Create a symbolic link from the sage project's directory to the Wordpress install
Activate the theme, go to the frontend and watch the chaos unfold

Temp-Fix:

Remove symbolic link to the sage project
Copy the files from the sage project to the WordPress install
Now everything works fine, but this is not really a solution

System info

Ubuntu Server 22.04 (happens on any other Linux / Unix / macOS, so it's platform independent) Wordpress optimized LAMP-Stack (not trellis) with Apache HTTPD and PHP FPM
