That’s not the unexpected part; I just mentioned it for completeness.

The unexpected behavior is that opening the application by clicking the icon 
sets default-directory to “/“ in the scratch buffer. This is true even though 
the process-level working directory is my home directory. It is also a change 
in behavior from 26.3.
