sublime_merge command on macOS not working as expected

[jammi]

Version info

• OS: macOS 12.5 Monterey and several earlier versions for as long as I've used Sublime Merge.
• Build: 2077 and every build I've used before that.

Description

The app's UI is frozen and is apparently actually running as a main or child process via sublime_merge rather than working similar to Sublime Text's subl command just commanding the UI app. Interrupting sublime_merge with Control-C in the terminal abruptly kills the entire UI app as well.

Steps to reproduce

Open a repository from the shell like sublime_merge ., then try to use Sublime Merge.app normally.

Expected behavior

The application is expected to function normally and sublime_merge to work similarly to subl does to Sublime Text. It should have a normal dock icon and react to clicks and keystrokes even when the shell proxy is paused with Control-Z or terminated with Control-C or even the entire Terminal.app being restarted, and its shells and their child processes along with that.
