Incorrectly defaults to higher port numbers

I'm submitting a bug report regarding how Live Server selects which port to use.

Current behavior

I used Live Server to test css changes for a flask app I'm working on. I ran the flask server on port 5500, the same as Live Server's default port 5500. While the flask app was running on port 5500 I started Live Server, which recognized that port 5500 was already in use so it opened to port 5501 instead. I then closed both servers and started Live Server, which opened to port 5501 despite port 5500 being available.

Failed attempts to resolve issue (in order):

• I closed the flask server and changed the Live Server settings.json file to include "liveServer.settings.port": 5500 but Live Server still opened to port 5501.
• I ran the flask server on port 5501 then started Live Server, which opened to port 5502. I closed both servers then started Live Server which opened to port 5502.
• I uninstalled Live Server to erase any potential port history, quit vscode, opened vscode, then reinstalled Live Server, but it now opens to port 5502.
• I ran lsof -i :5500 in the terminal to see if port 5500 was in use but it isn't.

Expected behavior

Live Server should:

• use the port specified in settings.json
• if no port is specified then use default port 5500
• if it is not available try the next incremental port until an available port is found

Others

This bug is not urgent. Live Server still works, it just annoys the everloving fuq out of me.

I resolved it! The .vscode settings.json was auto edited to "liveServer.settings.port": 5502 to push the ports higher. Thus the Live Server settings.json was overwritten.
