Restore all windows when closing them all at once

Does this issue occur when all extensions are disabled?: Yes/No

• VS Code Version: 1.60.2
• OS Version: Ubuntu 21.04 / Gnome

Steps to Reproduce:

1. Open two windows (optional : open folder/files, do some modifications and save them), then click on “Quit 2 Windows” to quit VS Code :

1. Open VS Code again : only the last active window is reopened (no matter what value is set in window.restoreWindows)

However, if VS Code is closed by another mean (like pkill code), on the second launch all windows are correctly restored. What is causing this behaviour, and how to fix it ?

We just trigger our quit function manually then:

I think the issue here is that the action in Linux closes the windows one by one. If we had a new event to override this behaviour and call our quit method it would probably work for us.

Ah I see the issue, we need a new event or existing window-all-closed event to be emitted for the context menu quit action ? What event do we use on Windows and Linux to determine quit action from File > Exit ?
