This seems broken again, maybe since the change to show the debug widget while initializing. Plus, sometimes it doesn't time out after failing to attach, so I'm stuck forever.

Launch this config with nothing running on that port, so it doesn't have anything to attach to:

{
    "type": "node",
    "request": "attach",
    "name": "Attach",
    "port": 9229
},

• Press F5, debug widget appears
• Clicking the red stop button or pressing shift+f5 has no effect
• I can't start another debug config while in this state
• Sometimes, it times out after 10s. But sometimes while trying this, it never timed out and I had to reload the window in order to debug
