Debug error steals keyboard focus from other windows

[bobbythehuman]

Behaviour

If your in a different OS window when an error occurs in a VSCode window 1, when trying to edit VSCode window 2, any changes you try and make occur in VSCode window 1.

This affects

• typing and deleting
• selecting use shift + arrow keys

It doesnt affect:

• selecting with mouse
• CTRL + C and CTRL + V

Steps to reproduce:

1. In VSCode have 2 windows open, and another window open on the desktop (paint)
2. In VSCode window 1 start the program in debug mode
3. Click over to paint
4. Wait until an error occurs
5. Click over to VSCode window 2
6. Try and type, anything that happens occurs in VSCode window 1

This wouldn't be caused by the debugger extension. It should be a VS code issue.
