open sketches in the current window, if no code has been written yet

Description

It would be great if Processing didn't need to open a second window if you run it first, then load a project (either directly or using the "open recent" function).

Expected Behavior

Loading a project with an empty editor loads the project in the current editor instance.

Current Behavior

A second Processing instance is created for the loaded sketch code.

Steps to Reproduce

1. Open processing by directly running the application
2. Load a project

Your Environment

• Processing version: 4.0b8
• Operating System and OS version: Win10 pro 21H2
• Other information:

As far as I understand, this is a different question. That duplicate is specifically about double-clicking a file, whereas this is about an already opened Processing window, and opening a project from File→Open Recent, and that leaving behind the useless empty sketch which you have to close every single time if you always open things with Open Recent.

Correct: this is specifically about not using a file browser to start Processing by double-clicking/activating a .pde file: First open Processing on its own, then use the "file -> open" or "file -> recent" menu options to load a sketch.

Sounds like a regression. This has worked properly at various points in the past; I may not have bothered re-wiring it properly when doing the handleOpen() rewrite.
