VS Code 1.46

• start VS Code Stable
• use this launch config:

  {
     "type": "node",
     "request": "launch",
     "name": "echo args",
     "runtimeExecutable": "echo",
     "args": [ "hello", "world" ]
  },
  

• close "launch.json" editor
• run it
• Observe: (everything is good)
  
• shutdown VS Code
• open same project with VS Code Insiders (or any other editor)
• modify "launch.json" and include argument "1234" between "hello" and "world"
• shutdown VS Code Insiders
• launch VS Code Stable again
• go to debug view and run "echo args" launch config
• open launch.json
• Observe:
  

VS Code runs old launch config which lacks the "1234".

Workaround: an edit change of launch.json is needed before VS Code will run the correct launch config.
