Issue

VSCode restores a previously closed DevContainer session when opening a new project, even when the --new-window flag is used and window.restoreWindows is set to none.

Steps to Reproduce

1. Open a project that uses DevContainers:

   code my-project
   

   Click the "Reopen in Container" popup.

2. Close the project using the window close (❌) button.

   • Verify that Docker containers have stopped using:

     docker ps
     

3. Open a different project in a new window:

   code --new-window my-new-project
   

4. Unexpected Behavior:

   • Two windows open:
     • One with my-new-project (expected).
     • Another with my-project reinitializing its DevContainer (unexpected).

Expected Behavior

• Only my-new-project should open.
• The previously closed my-project DevContainer session should not be restored.

Additional Notes

• This does not occur after a full OS reboot.

• The issue persists even with the following settings:

  {
      "window.restoreWindows": "none",
      "workbench.editor.restoreViewState": false
  }
